Like every other school in the country, St Teresa's College evaluates its students every term on what they have learnt, through internal examinations that prepare them for the BECE and the SSCE.
To uphold the principle of merit on which every educational system is built, and to keep the high standard expected by the founding fathers and the alumni, the college has a standing rule of "fail and fail out" and zero tolerance for examination malpractice. The College Handbook states:
Any student involved in examination malpractice of any shade whatsoever at any level shall face instant expulsion. Such a student shall not be entitled to any result or testimonial from the college, and the transfer certificate of a student in this category shall be marked "Expelled for Examination Malpractice".
