The New York Times yesterday published a scathing article about K12 Inc., the company that runs public charter school Hawaii Technology Academy in Waipahu, among other schools all over the country.

K12 Inc. makes a lot of money, NYT reports, but students at one of its largest charter schools are falling far behind.

We ran some quick numbers in our database of state assessment results from this year, and Hawaii Technology Academy students of all grades perform relatively well in reading. But they didn’t do so well in math, compared with their peers. May be a good idea to look further into it.
