Understanding the 4.33 GPA Scale
Why Some Schools Assign A+ = 4.33, What It Means for Your GPA, and How to Compare It with the Standard 4.0

What actually differs between the 4.0 and 4.33 scales

The difference between the standard 4.0 scale and the 4.33 scale is exactly one grade on exactly one grade designation: A+.

On the standard 4.0 scale, A+ earns 4.0 grade points — the same as a plain A. The grade designation "A+" appears on the transcript as a distinction, but it provides no GPA advantage over an A. The practical ceiling for GPA is 4.0 regardless of whether you earned A or A+ in your courses.

On the 4.33 scale, A+ earns 4.33 grade points — 0.33 more than an A. A student who earns A+ in every course has a GPA of 4.33 rather than 4.0. A student who earns some A+ and some A grades has a GPA between 4.0 and 4.33.

Every other grade point value is identical on both scales: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on. The 4.33 scale is not a completely different grading system — it's the standard 4.0 scale with a single change at the very top.

Full grade point table: 4.33 vs 4.0

The difference is entirely concentrated at A+. For any student who never earns an A+ grade, the 4.33 scale and the 4.0 scale produce identical GPAs. The scale distinction is only meaningful for students consistently earning the highest possible grade. For reference on what the 4.33 grade point value represents in isolation, see the 4.33 GPA scale page.

Which schools use the 4.33 scale

Canadian universities

Several major Canadian universities use the 4.33 scale. The University of British Columbia (UBC) assigns A+ = 4.33 in its undergraduate and graduate grading frameworks. McMaster University uses a 12-point scale that, when converted, effectively produces a similar above-4.0 maximum for top grades. University of Guelph and several other Ontario universities use variants of the 4.0 or 4.33 systems. Canadian universities' grading scales are not nationally standardized the way U.S. university scales tend to cluster, meaning that scale variation across Canadian institutions is greater than within the U.S.

Some U.S. high schools

A number of U.S. high schools use 4.33 as the grade point value for A+ in their unweighted GPA calculations. This is more common at private schools and some public high schools that chose to differentiate A from A+ in GPA terms. The prevalence of this practice varies significantly by district and state — many U.S. high schools simply cap unweighted GPA at 4.0.

Rare at U.S. colleges

The 4.33 scale is uncommon at U.S. four-year colleges and universities. Some sources have cited certain selective institutions as permitting GPA above 4.0 through A+ point assignments, but this varies by department and should be verified directly with the registrar. The large majority of American colleges use the standard 4.0 cap for A+, and this is what AACRAO's published grading guidelines reflect as the national convention.

How 4.33 changes GPA outcomes in practice

The practical GPA impact of the 4.33 scale depends entirely on how many A+ grades a student earns.

Scenario A: All A+ grades

A student who earns A+ in every course across a 120-credit-hour degree has a 4.33 GPA on the 4.33 scale and a 4.0 GPA on the standard scale. The 0.33 difference is the maximum possible separation between the two scales.

Scenario B: Mixed A+ and A grades (equal split)

A student who earns A+ in half their courses and A in the other half has a GPA of (4.33 + 4.0) / 2 = 4.165 on the 4.33 scale, versus 4.0 on the standard scale. The difference is 0.165 grade points — visible but modest.

Scenario C: Mostly A and A- grades, occasional A+

A student who earns A+ in 10% of courses, A in 60%, and A- in 30% has a 4.33-scale GPA of approximately: (0.1 x 4.33) + (0.6 x 4.0) + (0.3 x 3.7) = 0.433 + 2.4 + 1.11 = 3.943. On the standard scale, the same record gives (0.1 x 4.0) + (0.6 x 4.0) + (0.3 x 3.7) = 0.4 + 2.4 + 1.11 = 3.91. The difference is about 0.03 — negligible.

The key insight is that the 4.33 scale only meaningfully separates from the 4.0 scale when A+ grades are earned frequently. For most students — even very high performers — the practical GPA difference between the two scales is small.

How graduate programs read a 4.33+ GPA

When a graduate admissions committee sees a GPA above 4.0 on a transcript from a 4.33-scale institution, the interpretation is straightforward for anyone familiar with the system: this is a top-of-scale GPA, equivalent in competitive terms to a 4.0 from a standard institution.

Graduate admissions readers at research universities encounter students from institutions around the world using a wide range of GPA scales. A 4.2 from a 4.33-scale Canadian university is not evaluated as "better" than a 4.0 from a standard U.S. university in the same pool — both are read as "excellent academic record, at or near the top of the student's institution." The admissions decision factors that actually differentiate among strong applicants — research experience, statement of purpose, letters of recommendation, field-specific accomplishments — carry more weight at this GPA level than a 0.2 difference in scale conventions.

For applications to programs that explicitly ask for GPA on the 4.0 scale (as many U.S. applications do), a student from a 4.33-scale institution should report their actual GPA on the form and note in the additional information section that their institution uses a 4.33 scale. Entering 4.33 into a field expecting a maximum of 4.0 can create confusion in automated screening systems even if the human reader understands it.

How employers handle above-4.0 GPAs

Employment applications face the same interpretation challenge. Most online application systems set a maximum GPA field value of 4.0, which means a 4.33-scale GPA above 4.0 can't be entered as-is. The typical approach is to enter 4.0 (the equivalent ceiling) and note the actual GPA and scale in the resume or cover letter.

For employers who do GPA-based initial screening — investment banks, consulting firms, and some law firms that filter applications by GPA cutoff — a 4.0 entered for a 4.33-scale student correctly represents top-of-scale performance. No disadvantage accrues from capping the entry at 4.0; no competitive advantage comes from entering a literal 4.33 that the system may reject or flag.

Smaller employers and those less familiar with grading scale variation may encounter a 4.33 GPA on a resume and be confused by a number above 4.0. A brief parenthetical — "(4.33 / 4.33 scale)" — on the resume resolves the confusion. The same principle applies to any application context: always specify both the GPA and the scale maximum when reporting from a non-standard scale.

Converting 4.33-scale GPA to 4.0 standard

For a GPA between 4.01 and 4.33 on the 4.33 scale, the 4.0-scale equivalent is 4.0. These above-4.0 values represent A+ performance, which caps at 4.0 on the standard scale.

For GPAs at or below 4.0 on the 4.33 scale — which is the large majority of student GPAs — no conversion is needed. The values are identical. A 3.7 on the 4.33 scale is the same as a 3.7 on the 4.0 scale; a 3.3 is a 3.3; a 2.8 is a 2.8. The scales only diverge for above-4.0 values.

The GPA calculator and cumulative GPA calculator on this site use the standard 4.0 scale. For 4.33-scale institutions, these calculators still accurately compute GPA for any record that doesn't include A+ grades, and they produce a 4.0 maximum for records that do — which is the correct 4.0-scale equivalent of any A+ performance.

The 4.33 scale in high school GPA

High school GPA reporting is more complex than college GPA reporting, because high schools vary widely in their grading practices and the GPA that appears on a high school transcript may use the standard 4.0, the 4.33, or various weighted scales that go up to 5.0 or higher.

At a high school using the 4.33 scale, a student who earns all A+ grades in standard courses has a 4.33 GPA. At a high school using weighted GPA, the same student taking AP courses might have a 5.33 on a weighted 5.33 scale (4.33 + 1.0 AP weight). These GPAs are not directly comparable to each other or to college GPAs.

College admissions offices are familiar with this variation. They typically recalculate applicants' GPAs using their own standardized formula — converting transcript grades to a consistent scale (usually unweighted 4.0) — rather than using the high school-reported GPA directly. This recalculation normalizes for scale variation and grade inflation differences between high schools. The 4.33 or 5.0 GPA on the high school transcript is largely advisory; the college's recalculated GPA is what drives the admissions review. The guide on weighted vs. unweighted GPA: which matters for college covers the high school GPA comparison issue in detail.

The debate: does A+ deserve extra points?

The institutional disagreement about whether A+ should receive 4.0 or 4.33 grade points reflects a genuine philosophical difference about what GPA should measure.

The case for capping A+ at 4.0

The standard 4.0 scale treats A and A+ as equivalent in GPA terms. This position holds that the 4.0 represents "excellent" as a ceiling — the distinction between A and A+ is a qualitative one that belongs on the transcript as a grade designation, not a quantitative one that should inflate the GPA. From a measurement standpoint, if A and A+ both represent excellent mastery of course material, making them worth different GPA points implies a finer-grained distinction in quality than the assessment actually measures. A student who scored 93% and a student who scored 99% both demonstrated mastery — whether the 6% gap deserves 0.33 extra grade points is debatable.

The case for 4.33

Institutions using 4.33 argue that A+ represents a genuinely distinct level of performance — exceptional rather than merely excellent — and that a GPA system should reflect this. If a student earns A+ in every course, their GPA should show something that marks them as above the pack even among 4.0 students. The 0.33 spread at the top of the scale provides that signal. This position also has a practical fairness argument: students who push beyond A-range performance into A+ territory deserve a GPA benefit for doing so, just as students who earn B+ rather than B receive a GPA benefit.

Neither position has won universally, which is why both scales coexist. The lack of standardization means students and evaluators must always verify which scale applies and adjust interpretation accordingly. For practical GPA calculation purposes — computing how a mix of A+ and A grades affects semester and cumulative GPA — the GPA calculator provides a working tool, and the cumulative GPA calculator shows how grade history affects the running average across multiple semesters.

How to report a 4.33-scale GPA on applications

The key principle is to always include the scale alongside the GPA number:

• On resumes and CVs: "GPA: 4.33 / 4.33" or "GPA: 4.2 / 4.33 (University of British Columbia)"
• On application forms with a GPA field: enter your actual GPA. If the form has a "scale" or "maximum GPA" field, enter 4.33. If the form only allows a maximum of 4.0, enter 4.0 and explain in the additional information section.
• For below-4.0 GPAs on the 4.33 scale: no special treatment needed — values below 4.0 are identical to the standard scale. Just report the GPA normally.
• For graduate school applications: note in the additional information section that your institution uses a 4.33 scale if your GPA appears at or above 4.0.

For the grade point values of individual grades — how A- at 3.7 affects your cumulative GPA, or what a semester of B+ grades produces — the guide on how to convert letter grades to GPA points covers every grade from A+ through F with worked examples.

The 4.33 scale within the Canadian academic context

Canadian universities operate without a national GPA standard — unlike the U.S., where 4.0 has become the effective national default, Canadian institutions have historically maintained independent grading frameworks that include various scales (4.0, 4.3, 4.33, 9.0, 12.0, and percentage-based systems). The 4.33 scale is one variant within this broader Canadian patchwork.

UBC's grading framework

The University of British Columbia assigns A+ = 4.33 and publishes its GPA scale explicitly in its academic calendar. UBC also provides official conversion guidance for students applying to graduate programs that require 4.0-scale reporting. UBC's institutional recommendation is to report the GPA as earned (e.g., 4.15 / 4.33) and let the receiving program apply its own equivalence conversion rather than self-converting to 4.0. UBC's graduate programs accept applicants from both 4.0 and 4.33-scale institutions without penalizing either group.

McMaster University's 12-point scale

McMaster University uses a 12-point GPA scale that is distinct from both 4.0 and 4.33 frameworks. On McMaster's scale, A+ = 12 points, A = 11, A- = 10, B+ = 9, and so on downward. Converting a McMaster 12-point GPA to a 4.0 or 4.33 equivalent requires dividing by 3 (since 12/3 = 4.0), making a McMaster 12.0 GPA equivalent to a 4.0 or 4.33 top-of-scale on other systems. McMaster's system is effectively a stretched version of the 4.0 scale, not a fundamentally different framework — the underlying grade boundaries and academic standards are comparable.

The University of Toronto's approach

The University of Toronto uses letter grades with a GPA scale where A+ = 4.0 — capping at 4.0 like the U.S. standard. This means that within Canadian graduate schools, students applying from UBC (4.33) and students applying from U of T (4.0) present GPAs from different scales, requiring admissions readers to be aware of the institutional difference. Canadian graduate programs at UBC, U of T, and McGill have all developed institutional familiarity with this scale variation.

How U.S. graduate programs handle Canadian 4.33-scale GPAs

U.S. graduate admissions offices that regularly evaluate Canadian applicants — particularly at programs with significant Canadian enrollment, such as MBA programs at top U.S. business schools — have developed internal familiarity with the 4.33 scale. The standard practice is to read above-4.0 GPAs from known Canadian institutions in context, treating them as exceptional performance rather than attempting a mechanical conversion. When a U.S. application form's GPA field caps at 4.0, Canadian applicants with above-4.0 GPAs should enter 4.0 and use an additional information field or essay to note the institution's grading scale. For credential evaluation through WES or other official evaluation services, the converted GPA reflects U.S. 4.0-scale equivalences derived from the institution's grade distribution rather than a formula conversion. The GPA calculator can model how individual course grades aggregate under the standard 4.0-scale logic for cross-checking.

CGPA equivalences for Canadian professional schools

Canadian medical schools use the OMSAS (Ontario Medical School Application Service) GPA calculation, which converts letter grades to OMSAS equivalents for standardized comparison across institutions. OMSAS assigns A+ = 4.0 regardless of whether the originating institution uses 4.0 or 4.33 — effectively standardizing the ceiling. Law schools (LSAC) similarly convert transcripts to standardized LSAC GPA, where A+ from a 4.33 institution is converted to 4.0 for comparison. These professional application services have resolved the scale-variation problem by standardizing the conversion before any comparative ranking.

How to read a 4.33-scale transcript

When reviewing a transcript from a 4.33-scale institution, several things become immediately interpretable once the scale is known:

GPA above 4.0 signals A+ performance

Any GPA above 4.0 on a 4.33-scale transcript represents consistent A+ performance. A 4.2 means the student earned A+ in the majority of their courses; a 4.33 means they earned A+ in every course. This is the top tier of academic achievement — comparable to a 4.0 from a standard institution.

The 3.5–4.0 range: predominantly A performance

A GPA in the 3.5–4.0 range (below the A+ ceiling) indicates performance predominantly in the A and A- range. The scale behaves identically to the 4.0 scale in this range — a 3.7 on a 4.33 scale is the same as a 3.7 on a 4.0 scale. There is no scale adjustment needed when reading GPAs below 4.0.

Identifying scale from the transcript

Most transcripts from 4.33-scale institutions include a printed grade scale table that specifies the grade point values for each letter grade. If the transcript shows A+ = 4.33 in this table, the institution uses the extended scale. If A+ = 4.0 in the printed scale, it's a standard 4.0-cap institution. When the scale table is absent, checking the maximum GPA listed or consulting the registrar's website resolves the question.

When verification matters

For credential evaluation purposes (WES, ECE, and other NACES members), the evaluator will identify the institution's grading scale from institutional records and apply the appropriate conversion. Self-reported GPAs on applications should always include the scale denominator when above 4.0: "4.28 / 4.33" gives complete information; "4.28" alone invites misinterpretation. For GPAs below 4.0, the denominator is still useful context ("3.8 / 4.33") to confirm the reader knows the scale — though most evaluators will recognize these values as standard.

Academic thresholds and the 4.33 scale

Understanding where key academic standing thresholds fall on the 4.33 scale helps students at 4.33 institutions interpret their GPA in context.

Academic probation and the 2.0 minimum

At 4.33-scale institutions, the minimum GPA for academic good standing is typically still 2.0 — the same floor as at 4.0-scale institutions. Because the scales are identical below 4.0, the academic probation threshold is directly comparable across both systems. A student with a 1.9 GPA at a 4.33-scale institution is in the same academic standing position as a student with a 1.9 GPA at a 4.0-scale institution.

Dean's List and academic honors

Institutions using the 4.33 scale typically set Dean's List at 3.5 or 3.7 — thresholds derived from the standard 4.0 scale and carried over without modification, since most of the scale is identical. At UBC, various faculty honors designations use specific GPA cutoffs that reflect the 4.33 scale's upper range — a Dean's List requirement might be set at 3.9 or 4.0 specifically to include A+ earners, or at 3.7 to reflect solid A- performance as the honors boundary.

Latin honors equivalents for Canadian universities

Canadian universities generally don't use the Latin honors system (summa/magna/cum laude) that is common at American institutions. Instead, they use institutional designations like "First Class Standing," "With Distinction," or specific named honor recognition. At UBC, graduation "With Distinction" applies to students with a cumulative average of 85% or above in their final two years — a percentage threshold rather than a GPA cutoff, which sidesteps the 4.0 vs. 4.33 question entirely. At other 4.33-scale institutions, the specific honor designations and their GPA or percentage thresholds are institution-defined.

Graduate school minimum GPA

At 4.33-scale institutions, graduate program minimums are typically stated as 3.0 — the same as at 4.0-scale institutions. Because 3.0 represents B average on both scales (both set B = 3.0), the threshold is directly comparable without adjustment. Where a 4.33-scale institution sets a graduate program minimum at 3.3 or 3.5, that threshold also directly corresponds to its 4.0-scale equivalent, since those values are identical on both systems. Only at GPAs above 4.0 do the scales diverge — and no graduate program sets its minimum above 4.0.

Satisfactory Academic Progress on the 4.33 scale

Federal financial aid SAP requirements mandate a 2.0 cumulative GPA. At 4.33-scale institutions, the 2.0 floor is identical to the standard scale — both systems set C = 2.0, so the academic standing threshold is directly comparable. A student at a 4.33-scale institution with a 2.0 GPA is in the same academic standing position as a student at a 4.0-scale institution with a 2.0 GPA. The 4.33 scale creates no special advantage or complication for academic probation or financial aid SAP purposes below the 4.0 level. The guide on what is Satisfactory Academic Progress covers the complete SAP framework. For the detailed grade point values of all letter grades — how A- at 3.7 or B+ at 3.3 affect GPA calculations at any institution — the guide on converting letter grades to GPA points covers the full 4.0-scale reference table with worked examples applicable at any institution using the standard scale below 4.0.
