Education policy in my context

An educational policy in my context (Eswatini) is the to mainstream life-skills, ARH, STIs and HIV and AIDS and other disasters into the preset and inset teacher - training curriculum as a compulsory and examinable subject.
Policy makers are the teaching service commission.
Policy is set to raise awareness about the deadly HIV/AIDS at schools.
How does the TSC creates a course about HIV/AIDS while most schools do not approve of sex education.
