According to the guidance of the Ministry of Education and Training (MOET), training institutions when developing equivalent conversion rules need to comply with the following principles: Ensurequality; fairness, transparency, publicity, and unity; ensure science and practice; simplicity, ease of understanding.
The conversion framework provides scores for separate exams (APT, HSA, TSA...) and scores for high school graduation exam combinations suitable according to the dividing method based on the analysis of exam results of candidates with both separate exam scores and corresponding good exam subject combinations in 2025. The ranges of scores are ranked according to the top 0.5%, 1%, 3%, 5%, 10%... as in the following table:

The Ministry of Education and Training stated that the responsibility of the training institutions is to identify the graduation exam complexes in accordance with the characteristics of the individual test organization and recommend that other establishments can be used, which clarify which combination is most suitable. Announcing the section of the exam results in 2025 before May 31; At the latest 30.6 with the test results published after 31.5.
Coordinate with the Ministry of Education and Training to analyze the results of the high school graduation exam of candidates with separate exam results, on that basis, announce the scores of the appropriate exam subjects, no later than 3 days after announcing the results of the high school graduation exam in 2025.
Based on these figures, the admission scores and entrance thresholds of each major and specific major group will be converted linearly in each score range. For example, the admission score according to the A00 combination (T_A00) in the A2 - A3 range will be converted equivalent to the admission score according to the HSA (T_HSA) exam score according to the formula:
T_HSA = HSA3 + (T_A00 A3) × (HSA2 HSA3) / (A2 A3)
The determination of the difference in admission scores between common combinations will be based on a comparison of general scores announced by the Ministry of Education and Training after the results of the 2025 high school graduation exam according to each admission score range.
Regarding the framework for converting admission scores from high school academic results (academic records), the Ministry of Education and Training affirmed that it does not reflect the assessment results on a national unified assessment scale, so the development of a general conversion framework is meaningless.
However, the Ministry will publish statistics on the correlation between high school graduation exam scores and average scores of high school subjects, on which basis training institutions determine conversion rules equivalent to admission scores and entrance thresholds.
Based on the above guiding principles and conversion frameworks, training institutions will develop conversion tables and conversion formulas for each program, major, group of majors or training field, specifically as follows: select exams, combine exam subjects suitable for the admission methods of the program, major, group of majors, and training field.
For each separate test used, a separate table is needed. Each conversion table should only use the most suitable subject combination (exchange other combinations based on the difference in points).
You can divide the scores into more detailed ranges, or adjust the scores in the conversion framework in Table 1 to suit the requirements of each training program, major, and group of majors.
Develop conversion tables and formulas for admission scores according to exams not organized by domestic training institutions (for example SAT, ACT...) according to appropriate methods, recommend using the decentralization method.
Specific bases for training institutions to analyze statistical data (admission data from previous years, learning results of admitted students from different admission methods, admission combinations, common scores of exams...); consider the nature, difficulty, scale, common scores and characteristics of each admission method, exam scores, admission combinations when building conversion tables and conversion formulas.
