Betelle designed Vineland High School (now Landis Middle School) in Vineland, New Jersey. There is a good website dedicated to the history of the school, containing a nice overview of the Collegiate Gothic style Betelle employed:

“Exterior style was carefully chosen to blend and harmonize with surroundings. Modified Collegiate Gothic was favored by J. O. Betelle for reasons of scholastic character and other practical points that recommended it for use in a large city school like Landis School. In the Collegiate Gothic style, windows could be as high and wide as needed with a relatively small proportion of wall surface. Also, windows could be arranged irregularly without detracting from the general appearance. Collegiate Gothic was selected for economical reasons as well.”
