Status: NOT a miracle school
Main Reasons: Didn't have a 12th grade class so should not qualify, does not have high poverty, only about 20 students per grade.

This school should not be confused with the similarly-named Harmony Science Academy Austin. They are two distinct schools.

The inclusion of Harmony Science Academy North Austin on Newsweek's list of miracle high schools is baffling, since this school did not have an 11th or 12th grade in 2009-2010. Note that the Newsweek website is very explicit about the fact that their ranking is based on 2009-2010 data. The data are self-reported by the schools.

Here is what Newsweek says on its page explaining its methodology for the 2011 list: "In order to be considered for our list, each school had to complete a survey requesting specific data from the 2009-2010 academic year."

Despite these discrepancies, newspapers continue to reproduce the Newsweek data. For example, the Austin American-Statesman reported on June 24, 2011:
"The Harmony Science Academy in Pflugerville was among "Ten Miracle High Schools," included on the list that were singled out for additional recognition because they succeeded in educating and graduating a majority of low-income students who performed at high levels. In highlighting those schools, Newsweek hoped to point out what is working well in hopes that other schools would adopt similar strategies and practices.
The Harmony public charter school in Pflugerville has a small student body: just over 200 students with an average class size of 12 to 13 students per teacher, and 86 percent of the school's graduates enrolled in college. Sixty percent of students at Harmony qualify for free and reduced price lunch. Those figures are for the 2009-10 school year."

In fact the Texas AEIS report for 2009-2010 shows that this school had 14.7 students per teacher, slightly higher than the state of Texas average, which is 14.5.

The AEIS report shows 38.0% percent economically disadvantaged students, much lower than the state of Texas average of 59.0%.

Also, class size at this school is shown on the 2009-2010 AEIS report as generally around 21. (Note that class size is nearly always higher than number of students per teacher; they are two separate statistics.)

See the "Discussion" section for more details about the discrepancy between the data reported by Newsweek and that on the state of Texas AEIS report for this school.
