What is a contractual AP Computer Science teacher?

Contractual AP Computer Science Teachers are educators hired on a contract basis to teach Advanced Placement (AP) Computer Science courses, such as AP Computer Science A or AP Computer Science Principles, to high school students. Their responsibilities typically include preparing lesson plans, delivering instruction, assessing student performance, and helping students prepare for AP exams. Unlike full-time staff, contractual teachers may be employed for a specific term or number of classes, and their employment may not include full benefits. They are expected to have a strong background in computer science and a good understanding of the AP curriculum. These teachers play a crucial role in providing students with college-level coursework and helping them earn college credit while in high school.
