Our parent and teacher organization meets the fourth Tuesday of each month in the cafeteria at 7 pm.  Each meeting may provide a speaker or the opportunity to help with tasks that need to be accomplished for our school. If you attend, your child(ren) will receive a no uniform pass for the following Wednesday. We encourage everyone – parents, teachers, and even grandparents – to attend.

The women's society of Saints Peter and Paul Parish gather on the 3rd Tuesday of each month in the school cafeteria to further cement the bond of friendship and the devotion of of these ladies toward SS. Peter and Paul Parish.

The society supports many parish projects.  Its main objective has been to provide support for our parish school. Mary and Martha has given cash donations to cover textbook expenses as well as special needs identified by school staff. Monies contributed by the Society have provided items such as stage curtains, kitchen/cafeteria items, teacher item requests, and student scholarships. The Society coordinates the Box Tops for Education program, as well as an annual used book and video fair, rummage sale, country store, cookie walk, and Santa's Kottage.

The Holy Name Society is the men's parish group for Ss. Peter and Paul Catholic Church and Ss. Peter and Paul Catholic Grade School in Waterloo, Illinois. Our regular meetings are held monthly on the 4th Wednesday at 8 p.m. in the Ss. Peter & Paul School cafeteria. All men of the parish are welcomed at the monthly meeting.
