There might be lack of musical and arts experience and lack of resources. Lack of time to prepare performing arts and music lessons and not having enough time in the teaching day. Teachers might not have confidence to teach performing arts and music.
I will make sure that the HOD is aware of what learners can benefit from performing arts which is, it encourages learners to explore their emotions, expand their imagination and helps them develop their own unique voice. Also learners are able to express their selves and music boosts their self confindence. I will present all the positive things about performing arts to the HOD so that she can reconsider it.
