Before Applying

Incoming Freshmen
Current 8th grade students should register for the Diocesan High School Placement Test (HSPT). If you are taking the Diocesan HSPT you do not need to apply separately or send an additional fee to Saint Mark's High School. Although it is not required, families considering Saint Mark's are encouraged to fill out the Supplement to the HSPT. The $100 application fee to Saint Mark's High School is only for 8th grade students who did not take the HSPT or are applying outside of the established timeline or protocol.

The bottom portion of the Diocesan HSPT Registration Form will be used by Saint Mark's High School as your permission to release school records from your son or daughter's current school to Saint Mark's High School. We will automatically send a Recommendation Form to your son or daughter's current school along with your permission to release school records. Although you may send Recommendation Forms ahead of the HSPT test it is not required.

Extended Time: students requesting extended time on the HSPT should register for the Saturday test date only as there will be no extended time testing offered on Sunday. To request extended time please email the Director of Admission with a recent psycho-educational evaluation or other supporting documentation from a psychologist or qualified medical professional expressly defining the need for extended time. You can send requests to
