A formula for a successful school

This National Public Radio story on Brimley Elementary School in Brimley, Michigan should be listened to; but at least read the transcript.

Salient points below:

...
Brimley Elementary serves two groups that often struggle academically. Of the 300 students, more than half are Native American. Many come from low-income families.
...
At this school, American Indian students are outperforming other Natives in the state. The school as a whole performs above the statewide average for all schools, and on some tests, the low-income students are performing at the same level as kids from wealthier families.
...
First-graders who are having a tough time with reading and writing get one-on-one time with a specialist. There's an intervention teacher for kids in fourth, fifth and sixth grades — they mostly focus on math. There are teachers' aids to help out in all the kindergarten, first- and second-grade classrooms. And class sizes are small, averaging 22 kids.
...
There's one more thing. The teachers are constantly assessing their students to make sure they're where they need to be.
...
And based on the assessments, the bottom one-third of students get a lot of extra help and support.
