The school provides a British curriculum-based education system which includes the IGCSE Examination for grades 10 and 11 and International Advanced Level for 6th form.

The probe was a result of former UNP Member of Parliament and lawyer Dinesh Dodangoda lodging a complaint with the NCPA after failing to persuade the school to remove the book from its curriculum.

NCPA Chairwoman Anoma Dissanayake urged the Ministry of Education to take legal action against the school over the book's depictions of contraceptives, abortion and sexual intercourse.

The school continued to defend the book and refused to remove it on the grounds that it "educated children on sex issues so that they will be better prepared for the future".

[9][10] The events that transpired were reported on with special interest by the Colombo Telegraph, an online news publication that went on to release a series of articles in support of Rajawasan.

[11][12][13] On October 8, Rajawasan issued a public statement in which she further alleged that she was denied an opportunity for prefectship on the grounds that she chose to wear trousers instead of a skirt, which went against the school's uniform for girls.
