Will a teacher who maintains that her probationary period begins upon her appointment and not the date she receives her professional license prevail?

Yes. Carolina Castro began her appointment to teach science at DeWitt Clinton High School on September 3, 2003. From 2003 until 2009 she received satisfactory reviews and obtained her professional certification on September 1, 2009.

The DOE maintained that her probation began in 2009 and she received tenure effective September 1, 2013. Castro maintained that her seniority rights would be affected if the later date was used for her tenure date and she filed an Article 78 in Supreme Court.

The DOE moved to dismiss as the issue was moot since she had obtained tenure.

Justice Eileen A. Rakower granted the petition finding that the DOE action had no rational basis. Rakower did not deal with the mootness issue even though it does not appear that tenure is in any way affected by seniority.
