Absolutely. Performance-based classes are still classes that cover a certain curriculum. Some classes are based primarily on academic knowledge - those are the types that are most commonly associated with final exams. However, skill-based classes (music, art, drama, computer, physical education, etc.) can still have performance-based assessments. In choir, it could consist of reading music, sight-singing, or correct posture. In band, it could consist of correct fingering technique for a particular instrument, in physical education, it could consist of basic skills in a particular sport like tennis. If the computer class is a keyboarding (typing) class, then a final exam might consist of an evaluation of speed and accuracy, as well as keyboard layout. In a class focusing on computer literacy, a final exam might consist of demonstrating your skill by creating a spreadsheet, formatting a word processing document, or using hyperlinks. Anything that can be taught and learned can be assessed.
