Student-Teacher Ratios

At Reason, Nick Gillespie writes:

When it comes to teachers, in 2008 (the last year for which the federal government lists actual data), there were 15.3 pupils per teacher in public K-12 schools. That's the lowest recorded number. In 1998, the number was 16.4 and in 1978, it was 19.3. Over this same time period, the amount of money per student has increased tremendously and scores on the National Assessment of Educational Progress (NAEP) have stayed flat at best. Since 1970, the number of public-school students has increased by about 9 percent while the number of public-school employees (teachers plus everyone else) has increased by 96 percent. Something ain't right there. It seems quite plausible that states and local school districts can lose a good chunk of teachers without significantly impairing the quality (that may not be the right word) of K-12 public education.
