After 21 years as the superintendent of New Haven Public Schools, Reginald Mayo has announced that he will retire at the end of this year, effective June 30.

Mayo’s announcement confirms a previous News report that said the long-time superintendent would retire based on information from City Clerk Ron Smith. Mayo’s primary accomplishments include building the largest interdistrict magnet school program in the state of Connecticut, extending kindergarten school days and remodeling all 37 schools in the district.

“If I wait for the day to come when I no longer love overseeing this school district and looking out for the 21,000 public school children we serve, I might never retire,” Mayo said. “However, after 46 years of service to New Haven Public Schools, including the last 21 years as your superintendent, it is time for me to move on.”

His retirement comes on the heels of Mayor John DeStefano Jr.’s announcement that he will not pursue re-election this year. The two worked together on a number of initiatives, including the New Haven School Change Initiative.
