Vouchers improve graduation rates


A new report just released by the National Center for Education Statistics (NCES) reveals that students receiving vouchers in the D.C. Opportunity Scholarship program saw graduation rates that were 12 points higher than students who applied but did not receive a voucher. Better yet, students who won a voucher and then used it to attend a private school saw graduation rates that were 21 points higher than the control group.

The treatment group (students who won a voucher) saw a graduation rate of 82 percent.
The control group (which did not win a voucher, but of which 47 percent attended a charter school or private school anyway) saw a graduation rate of 70 percent — much higher than the District's official graduation rate.

The D.C district's graduation rate, according to NCES, is 56 percent.
The graduation rate for students winning and then using the voucher to attend a private school was 91 percent.

This all means that the effects of vouchers in D.C. are substantially understated by the report because nearly half of the control group exercised school choice. Unfortunately, journalists are unlikely to uncover these nuances and will instead report that vouchers don't work, despite the considerable scientific evidence that finds vouchers improve student achievement.

Bad news for high-tech education?


A new study by researchers at Duke University's Sanford School of Public Policy suggests that having a computer at home may actually lower student test scores, especially for low-income students. The study reports, "increased availability of high speed internet is actually associated with less frequent self-reported computer use for homework."

So what do kids use computers for? Playing video games and socializing with friends, of course. On the bright side, the study does find that parental monitoring of a child's computer use can lead to more productive time on the computer.

It is worse than we thought

NPRI published an article of mine yesterday (“Graduation time: Hold the celebration”) that highlighted the dismal state of affairs in Nevada public education. The article referenced recently released graduation data from the National Center for Education Statistics (NCES) and a 2009 report from Education Week. Today, Education Week has issued its 2010 report. In it, you’ll find no good news for Nevada.

According to Education Week’s “Cumulative Promotion Index,” Nevada’s four-year high school graduation rate has fallen from 47.3 percent to 41.8 percent, and is now 27 points below the national average. Over the last decade, Nevada’s graduation rate has fallen 23.9 points. (Note: The 2007 data is the most recent data available.)



Graduation rates fell among all subgroups, with Asian students’ 13.7 point drop representing the steepest decline. African-American, Hispanic and Native American student graduation rates all now sit below 33 percent.

Education Week also estimates that in Nevada, there will be 23,908 non-graduates this year alone. However, some of these students may graduate with a traditional diploma at a later date or leave with alternative credentials like a GED.

Nevada’s official reported graduation rate for the class of 2007 was 67.5 percent. Nevada uses a “Lever Rate” calculation, which is determined by dividing the total number of students earning a standard diploma by the total of the number of students earning standard diplomas or alternative credentials, plus dropouts. This may allow for additional graduates to be counted as it may not consider the time taken to graduate. According to Education Week researchers, state graduation rates are typically inflated because of poor-quality data on student dropout rates.

NCES reports a four-year graduation rate of 51.8 percent for the class of 2007. NCES and Education Week do not include CTE diplomas as standard diplomas when calculating graduation rates.

CORRECTION: After consulting researchers at Education Week, I learned that they include all graduates as reported by the State. So this would include the Career, Technical and Adult Education but not GEDs or certificates of attendance.

School district transparency



According to the Sunshine Review – a watchdog group that oversees government transparency – Nevada’s school districts receive a “D” for transparency.

The Sunshine Review finds, "No school district in the state managed an "A" grade. Washoe County School District ranked the highest with a "B", while Clark County School District received a "C" grade.” The worst school district appears to be Humbolt County.

Check out the Sunshine Review’s “Transparency Checklist” for more information on their methodology.

Red states vs. Blue states



Over the last 40 years there have been 139 separate lawsuits in 45 states over state funding of K-12 education. As a result, courts have deemed school finance systems unconstitutional and inadequate in 28 states, forcing those states to increase per-pupil spending.

However, it has now been several years since a state has lost an “adequacy lawsuit” – owing to the fact that much evidence suggests increasing spending has not resulted in greater student achievement. Nevertheless, two researchers – Christopher Berry, a professor at the University of Chicago, and Charles Wyson, a law student at Stanford University – writing for Education Next, set out to uncover how partisan control of state politics affects the allocation of resources following a state’s defeat in an adequacy lawsuit.

Examining spending levels in 23 states and 13,000 school districts between 1988 and 2005, the researches divided the states into three categories: states where the governorship and legislature were controlled by Democrats, states where politics was controlled by Republicans and states with divided governments. Each category was divided further into income groups: poor districts, two levels of middle-class districts and, finally, wealthy districts (each based on how many low-income students were in the district). The study produced some expected and unexpected results.

Not surprisingly, states under Democrat control experienced the largest increase in state spending for K-12 education. However, state increases in K-12 education were also offset by the largest decreases in local funding. Thus there was a trend among all income groups in Democrat-controlled states to centralize funding. Unexpectedly, however, was that the net increase – which was between $750 and $1,000 per pupil – was actually slightly higher in the wealthy districts than in the poorest districts.

Divided government produced smaller gains across all groups in terms of state spending, but the spending was clearly targeted to poorer districts. After subtracting local funding decreases, however, there was virtually no change in spending, although some districts actually experienced a decrease.

Republican control saw greater gains for poor districts, while Republicans also decreased state-level funding for wealthy districts – a result you might expect from Democrats. However, local funding increased for upper-middle and wealthy districts – something that did not occur under Democrats or divided government. The net increase in K-12 funding results in poor districts receiving more money than wealthy districts – something that did not occur in Democrat-controlled states. Although Democrats centralized spending across all income groups, Republicans appeared to centralize spending for low-income districts and decentralize spending for all other groups. It should be noted, however, that just three of the 23 states that lost an adequacy lawsuit were under Republican control.

The researchers conclude:

“Clearly, reforms implemented by Democrats produce the largest net increases in funding for all students. However, by delivering roughly equivalent funding increases to districts at all income levels, Democrat-led reforms do not target new resources to districts serving poor students. Reforms implemented by divided or Republican governments deliver concentrated benefits to districts serving poor students. In these instances, however, the actual flow of new dollars into poor districts is more meager than when Democrats are in control.”

Graduation time, for some



High school graduation is upon us as the school year comes to a close. Students graduating from high school should feel proud. Unfortunately, the National Center for Education Statistics' recent press release on state-by-state graduation rates gives a somber reminder of the occasion.

According to NCES figures, Nevada's average freshman graduation rate is just 51.3 percent - last in the nation. It is true that this number can be skewed downward because of migrating students, but the school districts haven't exactly opened up their student records for the media and researchers to see how many there actually are.

Additionally, Nevada's dropout rate stands at 5.1 percent - 24 percent higher than the national average.

Nevada can improve graduation rates and lower dropout rates by creating a better school system, attracting and retaining better teachers, and by ensuring kids can read by the end of the fourth grade.
