Trinidad and Tobago GPA Calculator: UWI 4.3 Scale

How the Trinidad and Tobago GPA Calculator Works (UWI 4.3, CSEC, CAPE)

The Trinidad and Tobago GPA calculator above runs two modes because T&T students need two different conversions. UWI 4.3 mode (the default) handles every Trinidad tertiary institution using the Caribbean 4.3 letter scale: UWI St Augustine in St Augustine, the University of Trinidad and Tobago (UTT) campuses in O'Meara, Pt Lisas, San Fernando, and Tobago, the College of Science, Technology and Applied Arts of Trinidad and Tobago (COSTAATT), the Arthur Lok Jack Global School of Business in Mt Hope, and the Caribbean Maritime University T&T outreach. CSEC / CAPE mode handles Caribbean Examinations Council secondary results when generating an admissions-style US 4.0 GPA from CSEC subjects and CAPE Units.

Both modes use the same credit-weighted average formula: each course grade point is multiplied by its credit hours to produce quality points; quality points summed across all courses are divided by total credit hours attempted. The result panel reports the cumulative GPA on the UWI 4.3 scale, the US 4.0 equivalent, the UWI Class of Degree (First Class Honours, Upper Second 2:1, Lower Second 2:2, Pass), and the UK degree class equivalent. This grade calculator is a UWI GPA calculator for UWI St Augustine transcripts, a UTT GPA calculator for UTT students, a COSTAATT GPA calculator when used with the COSTAATT letter scale, a Caribbean GPA calculator for the wider region, and a CXC GPA calculator when used in CSEC and CAPE mode.

Whether you searched for uwi gpa calculator, uwi st augustine gpa calculator, utt gpa calculator, cape gpa calculator, csec gpa calculator, cxc gpa calculator, gpa calculator trinidad, or simply gpa calculator from the gl=tt SERP, this tool covers the use case. The 3.60 First Class threshold, 3.00 Upper Second threshold, 2.50 Lower Second threshold, and 2.00 Pass threshold are the same across UWI campuses and UTT. What is GPA? Grade Point Average, the credit-weighted academic metric used at every credit-hour Trinidad and Tobago university and in most overseas admissions decisions.

UWI St Augustine Grading Scale, GPA Grade Bands, and Percentage Cutoffs

The University of the West Indies St Augustine uses the 4.3 grade-point scale across every campus and faculty. The scale was harmonised in 2014/2015 across UWI Mona, UWI St Augustine, and UWI Cave Hill, replacing earlier faculty-specific variants. The twelve-band scale below is the canonical reference per the sta.uwi.edu Examinations Section and the uwi.edu/gradingpolicy registrar page:

• A+ (4.30, 86 to 100 percent): Exceptional. The only letter grade above 4.00 anywhere in UWI; rolls back to 4.0 on US transcripts.
• A (4.00, 70 to 85 percent): Outstanding. Note that the UWI A starts at 70 percent at St Augustine, not the US 90 percent.
• A- (3.70, 67 to 69 percent): Excellent.
• B+ (3.30, 63 to 66 percent): Very Good. Typical upper-second band.
• B (3.00, 60 to 62 percent): Good. The Upper Second / 2:1 floor.
• B- (2.70, 57 to 59 percent): Satisfactory.
• C+ (2.30, 53 to 56 percent): Fair.
• C (2.00, 50 to 52 percent): Acceptable. The minimum passing grade and the UWI graduation floor.
• C- (1.70, 47 to 49 percent): Marginal Pass. Credits the course but may trigger prerequisite review.
• D+ (1.30, 43 to 46 percent): Conditional Pass. Limited credit on selected programmes.
• D (1.00, 40 to 42 percent): Conditional Pass. Programme-dependent.
• F (0.00, 0 to 39 percent): Fail. No credit; course must be repeated for prerequisite chains.

The UWI St Augustine percentage bands differ from those used at UWI Mona. Mona caps A at 80 percent and uses an F1, F2, F3 fail split; St Augustine sets A at 70 percent and uses a single F band with C-, D+, and D conditional-pass tiers between C and F. The grade-point values are identical across both campuses, so the calculator above produces the same numeric output regardless of which UWI campus the student studied at; only the percentage table on this page differs from the gpa-jamaica page.

UWI Class of Degree Thresholds and First Class Honours

UWI awards four levels of Class of Degree at graduation based on the cumulative GPA across Level II and Level III courses (Level I / Year 1 is weighted 0 percent in the official degree-classification calculation). The thresholds below are uniform across UWI Mona, UWI St Augustine, and UWI Cave Hill and apply to all undergraduate programmes:

The 2.00 cumulative GPA threshold is the absolute minimum to graduate from any UWI programme. Students below 2.00 are placed on academic probation; two consecutive semesters below 2.00 trigger mandatory withdrawal under UWI St Augustine Examinations Regulations. For graduate school applications to North American and UK institutions, a cumulative GPA of 3.00 (Upper Second 2:1) is the typical floor; competitive funded postgraduate programmes look for 3.30 and above. Commonwealth Scholarships, Chevening, and Fulbright awards typically require Upper Second Class Honours (3.00 or above) as a minimum eligibility threshold from UWI graduates.

How UWI St Augustine Calculates GPA: The Credit-Weighted Formula

Every UWI campus including St Augustine, plus UTT, COSTAATT, and Arthur Lok Jack, use the same credit-weighted average formula. The only difference across institutions is the per-course letter-to-percentage cutoff; the grade-point arithmetic is identical.

Two implementation details specific to UWI St Augustine matter for accuracy. First, Level I (Year 1) is weighted 0 percent in the final Class of Degree calculation; Level II and III courses determine the awarded Honours. The Level I weighting toggle on the calculator above mirrors this policy. Second, the UWI grade-replacement rule lets students retake a course graded F, D, D+, or C-; the higher attempt replaces the earlier one for cumulative GPA purposes (subject to a maximum of three retakes per programme). The calculator above lets you omit the lower attempt when computing your projected graduation GPA.

UTT, COSTAATT, Arthur Lok Jack, and Other Trinidad University GPA Scales

University of Trinidad and Tobago (UTT) GPA Scale

UTT uses the 4.3 grade-point scale with slightly different percentage cutoffs from UWI St Augustine. UTT aligns the A grade closer to the US 80 percent boundary on technical programmes (Engineering, Aviation, Process Engineering), and uses a finer-grained B / C band split for applied science programmes. The graduation threshold remains 2.00, and Classes of Degree use the same four-tier UWI structure (First Class Honours at 3.60, Upper Second at 3.00, Lower Second at 2.50, Pass at 2.00). The UTT GPA calculator workflow uses the same UWI mode above; the calculator returns identical grade-point arithmetic. UTT operates campuses at O'Meara, Pt Lisas, San Fernando, Valsayn, and Tobago.

COSTAATT (College of Science, Technology and Applied Arts of Trinidad and Tobago)

COSTAATT is a state-run college serving associate-degree and bachelor-degree programmes across business, IT, applied sciences, and allied health. COSTAATT uses a 4.0 framework for cumulative GPA reporting but maps letter grades onto the UWI-aligned 4.3 letter set for transferability into UWI St Augustine bachelor programmes. The COSTAATT GPA calculator path in the tool above defaults to the UWI 4.3 scale; COSTAATT students should select the equivalent letter grade and read the result, then cap the displayed value at 4.0 if applying directly within COSTAATT's internal reporting. The COSTAATT Dean's List threshold is 3.50 (versus UWI St Augustine's 3.60 First Class threshold).

Arthur Lok Jack, USC, TTHTI, and Other Trinidad and Tobago Tertiary Institutions

Arthur Lok Jack Global School of Business in Mt Hope is the UWI-affiliated graduate business school for the Caribbean; it uses the UWI 4.3 framework for MBA, Executive Education, and postgraduate Business Leadership programmes. The University of the Southern Caribbean (USC) in Maracas Royal Road is a Seventh-day Adventist institution using a 4.3 scale aligned with US Adventist institution conventions. The Trinidad and Tobago Hospitality and Tourism Institute (TTHTI) uses a 4.3 letter scale for its diploma and bachelor programmes in hospitality, tourism, and culinary arts. SBCS Global Learning Institute and ROYTEC offer UK university-partnership bachelor programmes that report results on UK degree-class lines but accept GPA conversion via the same 4.3 framework.

CSEC, CAPE and CXC Grading: How to Calculate GPA from CXC Results in Trinidad

The Caribbean Examinations Council (CXC) administers the CSEC (Caribbean Secondary Education Certificate, taken at Form 5 / Year 11 level) and the CAPE (Caribbean Advanced Proficiency Examination, taken at Form 6 / Year 12 to 13 level, equivalent to UK A-levels and US Advanced Placement). Both exams use a six-grade band, with Grade I as the highest. For overseas admissions or scholarship eligibility, these grades are converted to a US 4.0 scale as follows:

CSEC itself does not produce a Caribbean Examinations Council GPA at the secondary level; CSEC certificates list raw grades per subject. The conversion above is for admissions purposes only and is the mapping used by most North American universities and the UWI St Augustine Office of Admissions when generating an entry GPA from CSEC. UWI typically requires five CSEC passes including English A and Mathematics at Grade II or better for matriculation; competitive faculties (Medicine, Engineering, Law) expect Grade I across the relevant subjects plus strong CAPE results.

CAPE Unit results are treated identically to CSEC. Each CAPE subject runs over two Units (Unit 1 and Unit 2), with each Unit graded separately. UWI St Augustine accepts CAPE Units in place of A-level passes for matriculation. For US university applications, CAPE Grade I is treated as equivalent to AP score 5; CAPE Grade II as AP 4; CAPE Grade III as AP 3. UK universities convert CAPE results to UCAS Tariff points (CAPE Grade I = 48 points per Unit, equivalent to A-level A grade).

Convert UWI Trinidad GPA to US 4.0 GPA for Graduate School

Trinidad and Tobago graduates applying to US graduate programmes need their UWI GPA expressed on the US 4.0 scale. The conversion is mechanical because the UWI 4.3 scale already aligns with the US 4.0 scale at every grade except A+: UWI A+ (4.30) caps at US 4.0 since US transcripts top at A = 4.0 in almost every programme. All other UWI grade points carry directly: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0. The cumulative GPA cap means a UWI 4.30 across all courses reports as 4.0 on the US scale, but a UWI 4.10 also reports as 4.0; the small compression at the top of the scale is universal across credential evaluators.

For formal US graduate school applications, World Education Services (WES) is the most widely accepted credential evaluator for UWI St Augustine transcripts; the WES Course-by-Course report costs roughly USD 200 to 220 in 2026 and produces an authoritative US GPA. Educational Credential Evaluators (ECE) is the standard alternative, particularly for nursing and health-sciences applications. Both treat UWI bachelor degrees as equivalent to North American four-year bachelor degrees, and UK ENIC (formerly UK NARIC) recognises UWI St Augustine as a chartered Commonwealth university for UK postgraduate admissions purposes. UWI is a regional university recognised by the Association of Commonwealth Universities (ACU) and Universities Canada.

What Counts as a Good GPA at Trinidad and Tobago Universities

On the UWI 4.3 scale, academic standing and competitive thresholds follow a consistent pattern across UWI St Augustine, UTT, COSTAATT, Arthur Lok Jack, and USC:

• Dean's List or President's List: 3.60 and above at UWI St Augustine (semester GPA basis). UTT sets the Dean's List threshold at 3.60 on technical faculties; COSTAATT at 3.50; USC at 3.50.
• First Class Honours: 3.60 and above cumulative degree GPA at graduation (Level II + III only). Approximately the top 5 to 8 percent of each graduating cohort at UWI St Augustine earn First Class Honours.
• Upper Second (2:1): 3.00 to 3.59 cumulative degree GPA. The minimum classification for most competitive graduate-school applications and for the Commonwealth, Chevening, Rhodes, and Fulbright scholarship eligibility from UWI Trinidad.
• Good Academic Standing: 2.00 and above cumulative GPA. The minimum to remain enrolled at every Trinidad and Tobago university.
• Graduation minimum: 2.00 cumulative GPA. Uniform across UWI, UTT, COSTAATT, Arthur Lok Jack, and USC.

For overseas postgraduate applications, a UWI cumulative GPA of 3.00 (Upper Second 2:1) is the common floor; 3.30 and above for funded postgraduate programmes at top-tier US, UK, and Canadian universities. UWI St Augustine graduates routinely place into MIT, Stanford, Oxford, Cambridge, Toronto, McGill, Imperial College, and LSE programmes with cumulative GPA in the 3.50 to 3.80 range, supported by research and clinical experience built during the UWI degree. Government of Trinidad and Tobago state scholarships (administered through the Ministry of Education for outstanding CSEC and CAPE results) and the Higher Education Loan Programme (HELP) provide additional funding pathways for high-GPA T&T students.
