The Bryn Mawr Thorne Kindergarten at Haverford, which is based in a restored historic building on the Haverford College campus, was founded in 2004. The kindergarten offers a small, nurturing, child-centered, full-day kindergarten program that is especially appropriate for children with summer birthdays who might benefit from an additional year before attending their future elementary school. The class is staffed by a teacher, an assistant teacher, and undergraduate assistants.

Since 2004, the Thorne School has also offered a Language Enrichment Kindergarten (LEK) based at Haverford College. The LEK offers a full-day language-enriched kindergarten experience for children identified as at-risk for learning disabilities, with explicit instruction in literacy and math skills. It is staffed by a teacher, an assistant, a speech-language pathologist, and undergraduate assistants, with a student teacher ratio of about 3:1.
