Unlike the earlier comments I found the interim principle Nancy Wortmann to be competent, professional and well liked by the students and faculty. The one year wonder prior did a lot of harm and Nancy brought stability.

The current VP Kelli Smith was just named to the post and I hope she continues to make the practical decisions and provide the same leadership.

Yes there are occasions where small children "collect" things like items they find in lost and found and we diligently ensured our daughter learned the difference and alerted her 1st grade teacher, no more issues and those few in the class that seemed prone to collect things have been counseled and it stopped.

My daughter is the youngest in her class and that has a major impact on performance. The school assembed a team that has planned, invested and executed in an individualized program that has paid off big time. She loves school now, especially reading and her grades and performance is now on par with the best older students in the class.

Yes I wish the teacher to student ratio was better, but this school delivers and has a lot of reason for parents and studnts to show their Mustang pride. Close Quote
