Walter Williams explains how much public schools cost and how well they perform.

One of the most left-wing places in the country is Washington, D.C. – which votes 90% Democrat.

How good are schools run by Democrats?

Only 14 percent of Washington’s fourth-graders score at or above proficiency in the reading and math portions of the National Assessment of Educational Progress (NAEP) test. Their national rank of 51 makes them the nation’s worst. Eighth-graders are even further behind with only 12 percent scoring at or above proficiency in reading and 8 percent in math and again the worst performance in the nation. One shouldn’t be surprised by Washington student performance on college admissions tests. They have an average composite SAT score of 925 and ACT score of 19.1, compared to the national average respectively of 1017 and 21.1. In terms of national ranking, their SAT and ACT rankings are identical to their fourth- and eighth-grade rankings — dead last.

And how expensive are schools run by Democrats?

During the 2006-07 academic year, expenditures per pupil averaged $13,848 compared to a national average of $9,389. That made Washington’s per pupil expenditures the third highest in the nation coming in behind New Jersey ($14,998) and New York ($14,747). Washington’s teacher-student ratio is 13.9 compared with the national average of 15.3 students per teacher, ranking 18th in the nation. What about teacher salaries? Washington’s teachers are the highest paid in the nation, having an average annual salary of $61,195 compared with the nation’s average $46,593.

Public schools cost too much and perform too little.
