We have one PTO group for three schools. (K-1st, 2nd-3rd and 4th-8th grades). This was done about 4 or 5 years ago, it works really well for us. Although we deal with 3 principals, and a lot of staff between the three schools, everyone works very well together. The fundraising goes through all three schools and even the book fairs we hold are at all three the same week. We report things to the main school board each month as far as things upcoming, etc. We have a President (me), 2 vice presidents, a secretary and a treasurer. And a whole lot of parent volunteers! When dealing with three schools, you just need to think on a broder scale and we do things age appropriate. But the majority of our family nights are for all ages, BINGO, family olympics, etc.
I am thinking of joining two schools together for a pto group one school is very small only k- 1st grade, and the other school is 2nd through 5th grade and only a few has join the pto since its start up 3 years ago, i would like any feedback on if anyone else has done this in the past and how well was it received by parents.
