According to a December 31, 2002 editorial on Catholic Schools published in the New York Sun,
In 1962, New York educated a student population of about one million with about 40,000 teachers. Today, the city educates about 100,000 more students, but the number of teachers has doubled to about 80,000. Has the quality of education improved by a factor of two…?
The cost to educate the students in New York’s Catholic schools averages $3,200 a pupil for Kindergarten through eighth grade and $5,800 a pupil for high schoolers…. The public schools spend nearly double that, about $10,000 each in elementary and middle schools and more than $9,000 for each high-school student.
