Blog: Do Higher Teacher Salaries Equate to Higher PSSA & SAT Test Scores? Not According to Research Study

Do other factors make a difference in student test scores? What about teacher's experience and education? Spending costs per student? Parent's education?

Periodically I have posted about the Unionville Chadds Ford School District (UCFSD) and their ongoing teacher contract negotiation struggles of last year.  Deadlocked contract discussions required the PA Labor Relations Board to intervene and assist with the bargaining impasse. However, even after the release of the fact-finding report, it took months for resolution and the signing of a new contract.

After working without a teacher’s contract for over a year and weathering the contract negotiation process, a new contract between the UCFSD and the teachers was signed in September 2011.

Academically, there is a similarity between the UCFSD and T/E school districts – both districts are top performing school districts in the state.  On the SAT and PSSA performance, both school districts score in the top 1%.  In my post of September 21, 2010, I wrote that “T/E School District ranks #2 for SAT scores and UCFSD is ranked at #5.”  Using the high PSSA and SAT scores as a negotiating tool by the teachers union, I wondered if this was a tactic that would similarly be used in T/E and wondered if our school district could learn from the lessons in UCFSD.

All around we are seeing school districts struggling.  We are watching Delaware County’s Chester-UplandSchool District as they try to figure out if they can make their payroll next week.  Over in Bucks County’s Neshaminy School District, classes for 9,000 students are cancelled for the third day as their teachers strike. Having worked without a contract for four years, the teachers and the school board are battling over the contract and healthcare appears to be a major stumbling block on both sides.

If you follow Community Matters, you may recognize Keith Knauss as one of those that regularly comments on school district issues.  Knauss currently serves on the Unionville Chaddsford School Board and brings first-hand experience, especially when dealing with teacher negotiations.

Knauss prepared a report for his own school district, which he has graciously offered for Community Matters readers.  He looked at the 61 Philadelphia area school districts for factors that might explain the wide variation in academic achievement on PSSA and SAT tests.

Factors Knauss considered included:

  • Parental education
  • Poverty
  • Student to Teacher Ratio
  • Spending per Student
  • Average Teacher salary
  • Average Teacher experience
  • Average Teacher degrees

In his analysis of the data, Knauss uncovered some interesting results.  He discovered that “only two factors are significant – Parental Education and Poverty and those two factors alone can explain the bulk of the differences in academic achievement.”  Recognizing that “those two factors are beyond the control of the District”, Knauss notes that the “all other factors, where the District does have control over are not significant, including per student spending, class size, teacher salary, teacher experience, teacher education.”

While most of us might assume that the more experienced teachers, or those with the most education and the highest salaries would be factors associated with higher test results, Knauss research data does not support that theory, at least not in the 61 school districts in the Philadelphia area that he researched.  Knauss concludes, “contrary to popular belief, there is no evidence from the 61 districts that spending or the number of teachers has a measurable effect on academic achievement.”
