Certification Specialists has been helping teachers become New York State Certified since 2001. We provide services to both the New York City Department of Education and the City University of New York.

This guide is designed to assist candidates who are certifying to become Early Childhood and Childhood educators. Our guide includes practice problems for all aspects of the test. Introductory problems review foundational skills and three practice tests give you the opportunity to see your progress using mixed reviews that mimic the test. Detailed answer explanations have been refined based on our extensive experience building these skills with institutional and private clients.

Certification Specialists is a boutique test preparation company that specializes in teacher certification. Our materials are developed by teachers, for teachers and are based on extensive research of these exams.
