School Notes

  •  At Immaculate Conception Grade School, our commitment to excellence does not waver.  We understand the importance of setting high expectations and have resources in place (Math Specialists, Reading Specialist, classroom differentiation, classroom aides, social worker) to provide additional challenge or additional assistance to those students who might be in need of it.  Again and again, we hear from high school administrators how well prepared our students are.  Our curriculum is aligned with both the Diocese of Joliet and the State of Illinois learning standards.  Additionally we have been accredited by AdvancED, the world's largest accrediting agency.  
  •      At ICGS we recognize our responsibility to provide our students with a strong Catholic faith formation and varied opportunities for worship, prayer, and service.  As our students grow, we see their faith blossom and compel them to be people of action.  Consequently, our students will go out and make the world a better place.

Choosing ICGS for our daughters education was the best decision we have made as a family. The teachers and administration is top notch. My child has learned respect, compassion, faith, leadership along with an excellent education. IC is a family that we are proud to be part of.

ICGS was the best investment we have ever made. Along with excellent academics, our 3 children received an excellent faith foundation with an emphasis on Catholic leadership. They left the school with a solid sense of confidence along with a sense of their responsibility to make our world a better place. Each of them were well prepared in self-discipline and time management. As a result they have excelled in high school in the classroom, in athletics, and in extracurricular activities. This foundation was instrumental in providing them with excellent choices for college. We can't recommend this school highly enough.
