The New York State Education Department (NYSED) is requesting proposals from qualified vendors to plan, design, and deliver a training program employing the participant-centered case method system using a train-the-trainer model to implement new performance evaluations for principals. The training for principal evaluators will be provided throughout the contract period to superintendents, other LEA staff, BOCES staff, and key members of network teams who will then train evaluators of principals, most of whom will be LEA-level administrators.
