Diverse Curriculum

Our diverse curriculum will spark new interests and help you achieve your maximum potential. Our instructors offer challenges beyond classroom lectures. We have many classes to choose from beyond the state requirements. Some of our most popular classes include Fashion, U.S. at War, Journalism, Anatomy, Engineering/Infinity Project and Psychology.

College-level credit 

Courses for college-level credit are available through our strong Advanced Placement program and dual credit with LLCC and Quincy University. Honors courses are offered for students who excel. In addition, SHG offers classes with a more measured pace for those who may need academic assistance in certain areas.

HealthCare Programs

SHG partnered with St. John’s Hospital to bring an AthletiCare facility and program to the school. St. John’s staff and SHG faculty provide on-site education programming to interested students with a hands-on, immersive healthcare experience. Students work closely with therapists and physicians in a clinic setting. They also receive on-going healthcare seminars and fairs designed to increase their level of awareness about key issues in medical technology, healthcare practice, policy and education. Mentorship programs are available to students to create a greater level of involvement and support as they explore healthcare opportunities. 


Although our enrollment is approximately 685 students annually, you’ll find that our class sizes tend to be small and personal. Our student-teacher ratio is approximately 15:1, which ensures direct interaction and teacher attention.

Realizing the benefits of our personalized educational program, some of our students and teachers travel from the communities of Auburn, Chatham, Elkhart, Pawnee, Petersburg, Rochester, Riverton, New Berlin, Jacksonville, Morrisonville, and Farmersville. 

SHG is accredited by the Illinois State Board of Education and the North Central Association Commission on Accreditation and School Improvement (NCACASI). SHG is a member of National Catholic Educational Association (NCEA) and Dominican Association of Secondary Schools (DASS).
