While two-thirds of the Asia-Pacific countries surveyed are providing sexuality education pre- and /or in-service training to teachers, the quality and content are not known. All countries should develop country-specific curriculum for teacher training for effective, learner-centered comprehensive sexuality education (CSE) delivery, build competencies and skills of teachers with quality pre-service, in-service and refresher training as well as reference material, and promote supportive supervision, sharing and learning platforms for teachers delivering CSE.
