We used to get insurance through AIM but found out that all parent groups are covered under our district's umbrella policy. Yeah! Now we save over $300 per group and with 17 schools and the many booster groups at the high schools, it really helps us out.
We used to have AIM, but didn't get a renewal notice for this year, so we'll probably switch to PTO Today.
I'd be interested to know how many get their insurance through the district versus by yourselves, and if the latter, whether it's AIM, PTO Today, or something else.
