In an excellent post just released by The 21st Century Principal the author writes about yet another two companies calculating value-added for school districts, again on the taxpayer’s dime. Teacher Match and Hanover Research are the companies specifically named and targeted for marketing and selling a series of highly false assumptions about teaching and teachers, highly false claims about value-added (without empirical research in support), highly false assertions about how value-added estimates can be used for better teacher evaluation/accountability, and highly false sales pitches about what they as value-added/research “experts” can do to help with the complex statistics needed for the above
The main points of the articles, as I see them, pulled from the main article and in order of priority follow:
- School districts are purchasing these “products” based entirely on the promises and related marketing efforts of these (and other) companies. Consumer Alert! Instead of accepting these (and other) companies’ sales pitches and promises that these companies’ “products” will do what they say they will, these companies must be forced to produce independent, peer-reviewed research to prove that what they are selling is in fact real. If they can’t produce the studies, they should not earn the contracts!!
- Doing all of this is just another expensive drain on what are already short educational resources. One district is paying over $30,000 to Teacher Match per year for their services, as cited in this piece. Related, the Houston Independent School District is paying SAS Inc. $500,000 per year for their EVAAS-based value-added calculations. These are not trivial expenditures, especially when considering the other potential research-based inititaives towards which these valuable resources could be otherwise spent.
- States (and the companies selling their value-added services) haven’t done the validation studies to prove that the value-added scores/estimates are valid. Again, almost always is it that the sales and marketing claims made by these companies are void of evidence that supports the claims being made.
- Doing all of this elevates standardized testing even higher in the decision-making and data-driven processes for schools, even though doing this is not warranted or empirically supported (as mentioned).
- Related, value-added calculations rely on inexpensive (aka “cheap”) large-scale tests, also of questionable validity, that still are not designed for the purposes for which they are being tasked and used (e.g., measuring growth upwards cannot be done without tests with equivalent scales, which really no tests at this point have).
The shame in all of this, besides the major issues mentioned in the five points above, is that the federal government, thanks to US Secretary of Education Arne Duncan and the Obama administration, is incentivizing these and other companies (e.g. SAS EVAAS, Mathematica) to exist, construct and sell such “products,” and then seek out and compete for these publicly funded and subsidized contracts. We, as taxpayers, are the ones consistently footing the bills.
