A D.C. lawmaker introduced a bill Tuesday to prevent students from progressing to the fourth grade until they can read at or above a third-grade level.

The measure, sponsored by at-large Councilman Vincent Orange, would require students to take an “Annual Skills and Reading Diagnostic Assessment” at the end of each year, kindergarten through the third grade. If a student is not reading proficiently by the end of the third grade, the student will remain in that grade and be required to attend summer reading classes.
