Assumption Catholic Grade School, a Catholic elementary school located in the Archdiocese of St.
Louis, was established in 1871, for the purpose of educating the children in the newly founded parish in O'Fallon, Missouri.
Our school is committed to providing the children of Assumption and St.
Barnabas parishes with quality education, both in religious and secular areas.
Assumption School is firmly committed to teaching as Jesus did and living our faith in Jesus Christ and in gospel values.
The school prides itself in its openness to new trends in education and in a commitment to reach out to others in the local and global community through various service projects.
We offer Kindergarten (half day) through 8th grade from approximately 480 children from Assumption and St.
Barnabas Parishes. We are proud that graduates are consistently accepted into the high school of their choice.
There's much more to running a small private school than offering great academics and teaching. Be sure to check under the hood regularly to make sure everything keeps running smoothly.
Most adults find traveling more complicated and challenging that it was pre-pandemic. We offer some suggestions for safe teen travel in these uncertain times.
