Analysis of Cape Cod Lighthouse Charter School's scores missed the mark

To the Editor:

I am pleased to see your readers engaged in serious conversations about education on Cape Cod. I agree wholeheartedly with Jonah North’s contention that Student Growth Percentiles (SGPs) represent an important metric that should be closely tracked. I also share Mr. North’s admiration for the strong programming in the Nauset Regional school system. Surely, the combination of options available amongst the Cape Cod Lighthouse Charter School, the Sturgis Public Charter School  and the traditional public schools on Cape Cod make Cape Cod families the envy of the Commonwealth.

Mr. North, however, misses the mark in his analysis of the SGP scores at the Cape Cod Lighthouse Charter School (CCLCS). In English Language Arts (ELA), students from CCLCS outperformed students from Nauset Regional Middle School (NRMS) in the Composite Performance Index (CPI) at all grade levels. In addition, students from CCLCS outperformed students from Nauset Regional Middle School on the ELA SGP in 6th grade, the schools tied in 8th grade, and students from NRMS outperformed CCLCS students in the 7th grade. In math, CCLCS students had a higher SGP that students from NRMS in grades 6 and 7, and NRMS students had a higher SGP in grade 8. Clearly, these are both excellent schools.

Each year the Massachusetts Charter Public School Association calculates the test scores of  the weighted average of each charter school’s composite sending district. For the third consecutive year, CCLCS students outperformed students from the composite district at every test at every grade level.

In contrast to Mr. North’s contention, the Cape Cod Lighthouse Charter School continues to fly high in its 17th year of operation. As the only middle level public charter school on Cape Cod, we provide a solid alternative to the other excellent middle school choices available to families here. Aren’t we all lucky to live in a region where taxpayers and public servants work together to provide such great services to our students?
