In 1988, Francesco Perrulli founded Princeton Latin Academy on the conviction that there is no substitute for knowledge. Ideologies and political correctness are counter productive in the education of children. In 2002, he established Princeton Science Academy as a response to the faulty misconceptions in education about math and science without philosophy. This September, 2006, he inaugurates Princeton Lyceum, a junior school consisting of grades K-2, with a new classical curriculum based on modern linguistics. The school has an all-day kindergarten and after school care.

All three schools are located on the same campus in Hopewell, NJ, east of the junction of Route 31 and 518.
