School Notes

  • Academic excellence and Catholic identity are at the heart of St. Mary Catholic School. Our curriculum is oriented to create an individualized academic experience for each student.
  • Our faculty recognize that not every student has the same academic and emotional needs. Through our inclusive education mindset, we have the resources to support students with gifted capabilities and students with special needs.
  • Our curriculum emphasizes the basic skills necessary for each grade based on the State of Illinois and the Diocesan of Rockford standards. The curriculum ensures rigor, a commitment to Catholic education, and a prioritization of skills and standards.
  • Reading, English, math, spelling, science, social studies, and foreign language are taught at all grade levels. Our math and reading curriculums provide our students in grades K-8 the opportunity to learn at an accelerated level or receive additional academic assistance. Spanish is integrated into our kindergarten through fifth-grade core curriculums taught three times a week. Our sixth and seventh-grade students are also taught Spanish weekly as a specials class, and our eighth-grade students learn a year of French.

Our decision to have our children at St Mary's (Woodstock IL.) Was the best decision I have ever made. The school is Solid Catholic, Loving and always going the extra mile to serve with wisdom in mind, not to mention excellent academics. We Christians cannot offer to send our children to public schools- where they teach and encourage communism/ Marxist ideas. This school has a support program for those of low income like myself. My two little boys have never been so happy, making new friends and learning prayers, songs and much more.

Every parent wants the BEST for their child. Public vs private education can be a difficult choice in this economy.When my daughter was entering kindergarten I checked out ALL the options. I knew I wanted to start her education strong in order to establish a solid base for her future of learning. I wanted her to be in an environment that she would enjoy learning, get individual attention, be challenged, in a safe environment surrounded by friends and family with good character and strong morales. I am so thrilled to have chosen St Marys in Woodstock. It is everything I hoped for and more! This is not a government institution and is worth every dollar I invested and every sacrifice I have made to make this happen. Everyone involved including staff, families and children are OUTSTANDING!!! I have also enrolled my son in their pre-school program for all the same reasons. Thank you St. Marys!!!
