Leave Replacement Program

NJCTL's Leave Replacement Program helps districts that can't find an appropriately certified teacher to cover a long-term or short-term STEM vacancy.

NJCTL provides online asynchronous STEM courses for students and meets with them for live online sessions each week. This is combined with comprehensive, weekly coaching for the substitute covering the class.

The district provides the administration and classroom management; NJCTL provides the instruction and staff coaching.

Services Provided

NJCTL works with each district or school to customize a Leave Replacement Program that best accommodates their specific scheduling and staffing needs.

Throughout each assignment, NJCTL provides a skilled, certified instructor to support the substitute as well as online, asynchronous courses on its Moodle platform. These comprehensive courses include presentations, instructional videos by master teachers, frequent formative assessment questions, virtual labs, auto-graded quizzes, and tests.

The NJCTL instructor will grade work submitted by students, answer questions, and facilitate in-class discussions. The instructor also works directly with the substitute teacher to plan the dally agenda for each class.

NJCTL does not act as the teacher of record and is not acting as an employee of the district. NJCTL’s primary role is to provide comprehensive content support. The substitute teacher will handle classroom management and serve as a liaison to administrators and parents.
