Class 6 to class 8 pupils are the senior pupils in the school and are undertaking the 8-4-4 curriculum. The 8-4-4 system is the older curriculum in which the pupils take 8 years in primary school, 4 years in secondary and 4 years in university. This curriculum is mainly focussed on academic performance more than skills building. The classes have 4 streams each with an average of 35 pupils per class. The pupils are managed by 33 teachers who aim to see them attain academic excellence

There is a senior teacher in charge of the upper primary who is in charge of observing discipline. According to the new curriculum(CBC), upper primary will entail the grades 4, 5 and 6. As the government continues to roll out the CBC , SPA is well prepared as it purposes to ensure the classes 6, 7 and 8 pupils finish their studies successfully and  embrace the new upper primary group.
