"I develop lessons, look at action plans, and [YOU NEED A VERB HERE--MAYBE 'MAKE USE OF'?] other types of data to ensure the success of each student." Or else say "Careful use of action plans and other data enable me to design lessons that ensure the success of each student." But can any lesson really ENSURE success? I think you mean increase the likelihood of success.
"I am pleased with the small-town atmosphere, and the high level of parental involvement." To me, this sounds condescending (who cares if it pleases you?). How about "Working in a district such as yours, with its small-town atmosphere and high level of parental involvement, would be an excellent complement to the personal attention and support I try to give each child."
