THE MINIMUM SCORE PREDICTION FOR CONSORTIUM OF THAI MEDICAL SCHOOLS (COTMES) FACULTY QUALIFICATION BY N-METHOD IN YEAR 2021-2023

Abstract

Thai university Central Admission System (TCAS) is developed for all high school students in Thailand. There are four rounds of TCAS called, portfolio, quota, admission and direct admission. The admission round is the round that use the score of each test subject to compute the total score, and then apply to TCAS. Consortium of Thai Medical Schools (COTMES) is a group of the Faculty of Medicine, Dentistry, Veterinary Medicine and Pharmacy for selecting students through the admission round of TCAS system by using the same score criteria. The minimum score that can qualify the admission is the main point. However, the last year minimum score cannot be used directly because of the difficulty of the tests in each year. The researchers have developed a model called 𝑚𝑒𝑎𝑛 + 𝑁(𝑠. 𝑑.) model or N-Method to predict the minimum score of COTMES faculties. The results show that the error means of the year 2021,2022 and 2023 of all majors are between -0.7645 and +1.4505. For only Faculty of Medicine, the error means are between -0.6477 and +1.9227. Faculty of Dentistry, similar result to Faculty of Medicine, the error means are between -0.5388 and +1.2261. For Faculty of Veterinary Medicine and Faculty of Pharmacy, the error means are from -2.8003 to +3.3976 and from -4.0377 to 4.7310 respectively.
