College Preparatory School for Girls Grades 3-12


The school day begins at 8 a.m. Please have your daughter to school on time – we recommend you drop her off by 7:50 a.m. each day. This enables her to have time for morning interactions with classmates and teachers, settling in without rushing. If you are running late, or if your daughter will be absent, please notify the as soon as possible: Lower School Office 301.365.6063, Middle School Office 301.365.6017, or Upper School Office 301.365.6045.

Lower School parents receive two cardboard placards with your carpool number in August. Please place a placard in your car(s) for use during carpool pick-up. Cell phones may not be used during carpool. Please obey posted traffic signs and all directions given by our Facilities Staff.

The School's 2001 Neighborhood Agreement restricts Holton traffic in various ways and the School strongly encourages families to carpool. It is important that Holton reduce the traffic to campus.
