The success of the PSI Endorsement Programs has led to an interest on the part of currently certified teachers in science and math to learn about the practices that make PSI so effective, and how to apply those practices in their classrooms. Towards that end, CTL is offering professional development (PD) opportunities that offer a meaningful exposure to our approaches and strategies at a lower cost and time commitment on the part of those teachers. Working in cooperation with Kean University, those interested may take these courses for either professional development hours or graduate credits.
