If you've already been fingerprinted by New York State, the OSPRA 103 is the form that you complete to authorize New York State to send your fingerprints to New York City.
Note that very few candidates need to file the OSPRA 103. However, if you have worked in school districts or completed student teaching in a New York school district other than NYC Public Schools, it is possible you will fall into this category. If you are not eligible to complete the OSPRA 103 form but do so anyway, your onboarding will be delayed.
Upon completion of the OSPRA 103, it should be submitted via email to HRCServiceCenter@schools.nyc.gov.
