Who's in the PTA?

Not quite as many parents as I might have expected, but then I'm always amazed at how low voter turnout is as well. Here are the percentages of parents who have joined PTA, broken down by grade:

Pre-K: 48%
K: 60%
1st: 48%
2nd: 56%
3rd: 29%
4th: 37%
5th: 31%

I would have guessed that Kindergarten would have the highest (pre-K feels slightly off the bubble to me) and that 5th grade would be the lowest. There's certainly a downward trend, but the real news is the drop from 2nd grade to 3rd grade. If I were PTA president, I would try to figure out the disconnect there: lower percentages for those kids when they started K, higher number of new students in that grade, or perhaps different PTA leadership when those students started. It will be interesting to note how current class of Kindergarten tracks as they make their way to 5th grade.
