The most direct routes by subway and bus are to take the subway to 23rd Street and then the M23 bus to Tenth Avenue. The Broadway (N/R), Lexington Avenue (#6), Sixth Avenue (F/M), Seventh Avenue (#1) and Eighth Avenue local (E) trains all stop at 23rd Street.
Although probably a longer ride, the M11 bus will also bring you close to the school.
If walking after getting off at the 23rd Street stop, walk west on 23rd Street to Tenth Avenue, then turn right (north) onto Tenth Avenue and walk two blocks to the school.
