Of the Portland public schools that had marked changes in their test scores this year, Northeast Portland's King School, a K8 institution, had the biggest change of all. The school has seen dramatic growth and decline in test scores for the past several years.
Several other schools had similar trends in the report that was made public Thursday, but King stood out.
In 2010, 40 percent of fourth graders passed the state’s standardized math test scores. The next year, the scores skyrocketed – 89 percent of fourth graders passed.
