Student Participation!!!


Is there a correlation between successes in the classroom with student participation in extra-curricular activities? This question has been asked over and over again.


I recently asked Mr. Nowotny our activities director to give me the lists of high school students who participate in Fine Arts and in Athletics here at St. Thomas More. The numbers of students who participate for STM are staggering! We have 142 students who are participating in Fine Arts this year, along with 180 students who are participating in athletics. The number that jumps out to me is that we have 88 students who participate in both Fine Arts and Athletics. Considering that we have 238 students attending St. Thomas More, this is an incredible number. I am so proud of our students and families, it takes a village to raise our children and you as parents have done a wonderful job.


So is there a correlation? The answer would be YES, we have 98% of our student body participating in something for our school. We have 98% of our students who go to a 4 year college. Our average ACT score is 25.3 this is 5 points higher than the national average. The correlation would be that our students know how to put the time and effort in the classroom and in their extra-curricular activities. We have seen success in with our students in both areas of scholarships that have been given for academics and extra-curriculars.


I also believe that when students compete in the academic and extra-curriculars, they start to take pride in their school and everything that is associated with the school. I am grateful to be a part of such an amazing school and it is a blessing to watch your children flourish and accomplish their goals.    


St. Thomas More families, there are many ways that we as a school can earn money without having fundraisers! I will list a few items that can earn money for our school that I am sure you are doing and do not even realize the potential of income for our school. They are:


  • Family Thrift receipts- for every $150,000 dollars of receipts our school receives $1,000. (We are only $10,000 short of another $1,000!)
  • Every top of “Land of Lakes Milk” is worth - $.05
  • Every “Our Family” upc code is worth - $.05
  • Every “Box Top for Education” is worth - $.10


If you simply send in these items we will have groups such as “Student Council” and “National Honor Society” at our school adds them up and then we collect the monies for our school. It is that easy! We appreciate your support.



 “It’s easy when you know how”


Have a wonderful month and may God Bless you and your family.


God Bless,

Mr. Sullivan
