Under New York State law, appointed teachers achieve tenure after completing a probationary period (usually four years and a day). In New York City, tenure is granted in your license appointment area. Having tenure means you may not be disciplined or terminated without due process for reasons other than failure to complete the requirements for your professional certificate. As a tenured teacher, you have the right to a hearing before an independent arbitrator regarding any charges brought against you. This due process right protects you from being fired for personal, arbitrary or political reasons.
