Here is a link to NC school report card data. It is a state site, state data. The numbers do not tell all, but they give some pretty good indication of how a school is "doing" in relation to the other schools in the district, and those in the state.
NC School Report Cards
Choose a school or a district, and then click on the "high student performance tab" If you decide on Havelock, TCMS had 56 students take high school algebra (this year, not yet on report card), and had 100% pass, for high school credit. The state average is in the high 70's, so....that tells you something.
