To better prepare each student with the tasks, activities and responsibilities that lay ahead, each must pass both written (conducted on the 3rd Saturday of February) and oral (conducted on the 2nd Saturday of March) entrance examination.

All applicants must be part of the upper 10% of their graduating class and must have at least a grade of 85% in Science, Math, and English and 83% or above in all other subject areas in any grading period or the equivalent grade as to the grading system used by a school as duly certified by its principal. Pupils graduating from Science Elementary Classes are required with a grade of at least 83% in Science, Math, and English and 80% in all other subject areas.

The examination is in Science, Math and Mental Ability with which the examinee must get 83% and 80% of the total score in Science and Math, respectively, and at least an above average IQ. Hence, all successful examinees qualify for an interview that tackles all subject areas. The screening committee determines the top 175 students (formerly 140) who have to confirm for enrollment. Finally, all 175 enrollees should attend the school's orientation program as scheduled together with their parents or guardian.
