Welcome to Mundelein High School

Brochure_ImageThis is an exciting time for eighth grade students, transfer students and parents as you prepare for the transition from your current school to MHS. We understand that this new beginning can be fun and stressful at the same time. This section of the website will help take away any of the stress and leave just the fun. By making this section of the website your new “Home,” you will be able to have many of your initial questions answered and learn about the many ways that students new to MHS can soon learn to feel “at home” here. The booklet below, in both English and Spanish, will provide an initial overview of the rights and responsibilities of MHS students along with information about clubs, activities, and sports that you are encouraged to consider.

Welcome to Mundelein High School

M_red_logoWelcome to Mundelein High School!  We are very excited that you will be joining the MHS family. We are looking forward to assisting your student in making the important transition from middle school to high school. On Thursday, January 18th, we are hosting our Class of 2028 Incoming Freshmen Night at Mundelein High School for both families and students. The program will include an overview of our academic programs, course placements, information on the day-in-the-life of a ninth grader, and extracurricular opportunities at MHS.

Both parents and students are invited to attend. Incoming ninth graders will meet with high school students to learn more about what they will experience as they transition to MHS. Topics such as classes, activities, athletics, and special events will be discussed. Students will also have an opportunity to ask questions about the transition to high school.

We ask that parents/guardians and students with last names A-L arrive at the MHS auditorium by 6:00 PM for a 45-minute presentation. Parents/guardians and students with last names M-Z should attend the 7:15 PM session in the auditorium. The presentation will be offered in Spanish in the cafeteria during both sessions. Spanish-speaking families can also use translation headphones for the presentation in the auditorium.

Following the presentations, we will host our Activities/Athletics Fair, where sponsors, coaches, and students will be available to speak about their respective clubs or sports, answer questions, and enlist future members. In addition, department chairs and other administrators will be available to answer any questions you may have about the transition to high school.
