I would never consider the SMCPS "top notch". If you want to say they are on or above the norm, that would be accurate but also not something to be terribly proud of.
The school system faces several problems in recruiting teachers.
1. pay
2. locale
3. mandated diversity.
1. Pay: based on something I read in yesterdays paper the pay for a teacher in St. Mary's county is not out of line with a number of districts, then again these are not the "top notch" school systems you want to compare yourself to. When you look at the surroundling area, the pay for a teacher in St. Mary's is not attractive.
2. Why would a young, single individual want to relocate to St. Mary's Co? Can they find good, affordable housing on their salary?
3. The state of Maryland is anal about it's diversity numbers, both for students and employees. What does that mean for SMCPS? If the state hold true to form, they will hold the lack of a diverse workforce against the school, read they will not give them grants etc - $$
4. I know, a new one. Unlike a lot of areas, SMCPS don't really have dedicated source of funding. The primary "source" is the county governemnt. The school board can vote on a budget, but in the end it's the county commisioners who provide the funds. They (SMCPS) can also apply to the state for grants and other funds (capital improvements). In some states, the schools raise their own revenue via taxes. The local school board has the power to levy taxes (within state law). Additionally the state will proide funding but it's done a formula based on number os students. It's an amount that school board can estimate with some accuracy for the purposes of their budget.
