OVERVIEWThis page is for incoming Freshmen whose Admissions letter stated that Summer School is "required." (This page is not for students who were recommended)

  • High School Preparatory Reading

Students who are required to attend Summer School may also benefit from our High School Preparatory Science Readiness course for added preparation. 
Our experienced instructors will guide your student towards mastery of the skills they will need to be successful in high school. We look forward to a successful Summer!

    • Students who are required to attend Summer School should plan to attend classes on the MD campus Monday June 21st-Friday July 23rd.

  • Students taking HSP Reading, HSP Language & Writing, and HSP Math start at Period 1 or Period 2
    • If you have a request for start time or student will be participating in an athletic camp, please note this on the registration form (e.g. "request period 1 start" or "will participate in boys soccer"). We will do our best to honor requests. 
  • Students taking HSP Reading, HSP Language & Writing, and HSP Math AND Science Readiness will have classes from Period 1- Period 4
    • Classes are short and there is a lunch break, so many students find 4 classes manageable 
example registration note: student will participate in baseballIt is important to be available during the class time. If there is a certain period or period(s) that your student cannot be available or if they have other potential scheduling conflicts, such as a sport, please be sure to note this on the registration form. We are able to accommodate many scheduling requests if listed with registration. 
Students will need a laptop, tablet (any kind), or Chromebook to complete their Summer School work. MDHS will not check out devices to students for at home use in Summer 2021. 
MDHS will provide free campus WIFI to students. 
*Applies only to incoming 9th grade students required to attend Summer School: If your student will need an electronic device for use in the classroom (only), please indicate this in the Registration Notes. MDHS electronic devices will be limited in quantity and will need to remain in the classroom. 
The High School Preparatory courses are taken for preparation and to meet placement requirements, not for credit. Completion of these courses will be reported to Department Chairs for placement and will be noted on the student's Mater Dei High School transcript. HSP courses do not count for credits or factor into a student's GPA. 
In some cases, taking the Incoming Freshmen courses, may improve your placement for the upcoming school year. For example, students who have been required to attend High School Preparatory Reading for Summer School may be able to place out of taking Reading during the school year. 
We are not able to offer accommodations during Summer School. These include, but are not limited to, additional testing time, testing in our Learning Center, test readers, note takers. 
Our Incoming Freshmen High School Preparatory courses are designed for students who need more help with the subjects and the pacing and exams take this into account. 

If a class is cancelled, or the student drops a class prior to the first day of Summer School (June 21st 2021- must notify by June 20th 2021), fees will be refunded in full. If the student drops a class during the first week of summer school (June 21st- June 25th 2021), 50% of the fees will be refunded if the Summer School Office is notified that the student is dropping the class by June 25th 2021. There will be no refunds for class(es) dropped after June 25th 2021. Classes will only be dropped when the Summer School Office is notified a student will no longer be attending. If a student is expelled from Summer School, no refund will be given.


No refunds will be issued if the student does not contact the Summer School Office by June 20th 2021 to correct any errors in course enrollment (e.g. student registers for Algebra 1 when Algebra 1A is needed, or 1st semester when 2nd semester is needed). Please consult your Academic Counselor prior to registering for Summer School if you are unsure of which course(s) or semester(s) to select. If you realize that you have registered for the wrong course or semester, please contact us by June 20th 2021.


No refunds will be issued if a student does not earn credits for a course and/or does not earn their desired placement(s) for the next school year. Students should contact the relevant Department Chair to ensure that they will receive credit for a course and are aware of placement requirements.
