APT is one of three research-based measurement tools that make up the APAS System, a field-tested, user-friendly suite of evaluation tools built with OST in mind. Use APT to measure the quality of your program, identify the areas where you are succeeding, and pinpoint areas to improve. APT will give you a clear picture of your program by collecting data on practices that are linked to three key youth outcomes. 1. Learning and Skill Building 2. Program Organization and Structure 3. Supportive Social Environment. 

How does it work? APT relies on two data-collection methods -- the observation tool (APT-O) and the program questionnaire (APT-Q). These two methods combined allow APT to look at the overall OST program, including homework time and activities. 1. APT-O focuses on observable program practices. a. There are two versions of the APT tool (K-8 and Teen). 2. APT-Q is completed by program staff and examines “behind the scenes” aspects of program quality. (author abstract)
