On 12 April 2011, SMKA Kota Kinabalu became a School Without Litter through a proclamation issued by Kota Kinabalu City Hall. In 2016, SMKA Kota Kinabalu becomes an SMKA with the status of Maahad Tahfiz (school of al-Quran memorisation) and, thus, offers Tahfiz programme to students.

The name of classes has no turning as the name of classes is usable every year. Currently, the name of classes in the school is Bukhari, Muslim, Abu Daud, Tarmizi, An-Nasaie and Ibnu Majah (obsoleted).

However, the pre-university classes have no name as they use the course taken as the class name.
