I give teachers options.

1) pay tuition and a holding fee, sept to june. with no care over the summer.

2) pay tuition, sept to june and a holding fee july and august. with no care over the summer

3) pay a prorated tuition fee all year. can come 8-4pm on tue, wed, thur over the summer.

The need to decide when signing the contract. They can change for the following year (sept) when they renew their contracts in June.

PD days etc. during sept to june are regular contracted hours.

Hours
Sept to June: reg hours 8 - 4, or extended 7:30 - 5
