The work-based learning coordinator extension certificates serve to extend the base certificate held by the teacher. In NYCDOE, a teacher must hold an Initial or Professional certificate in order to apply directly for the WBL Coordinator Extension certificates through the New York State Office of Teaching Initiatives. For teachers who hold a Transitional A certificate, the extension certificate will match the type of certificate held. The extension title will progress as the base certificate progresses from Transitional A to Initial, and Initial to Professional. In the NYCDOE, the WBL Coordinator extension is not a teacher of record title and does not have a corresponding city license title and therefore no School District Recommendation is provided and any applications under this title will not be completed through your HR Director. In order for an already certified teacher to apply for the WBL extension certificate directly an Initial or Professional certificate must be held. Additionally, documentation must be provided to verify of a minimum of 300 or 600 clock hours of work experience outside of the classroom.
