An Update on New Jersey’s SGPs: Year 2 – Still not valid!

January 31, 2014

8

I have spent much time criticizing New Jersey’s Student Growth Percentile measures over the past few years, both conceptually and statistically. So why stop now. We have been told over and over again by the Commissioner and his minions that New Jersey’s SGPs take fully into account student backgrounds by accounting for each student’s initial […]

Segregating Suburbia: A Princeton Story

October 30, 2013

16

Others around me have for some time been raising concerns about the emergence of boutique, suburban charter schools. Until now, I’ve largely blown off those concerns in part as I’ve questioned just how much sorting a charter school can achieve in a relatively homogeneous suburban area. Suburbs have their own unique portfolio of schools.  One […]

Newark Charter Update: A few new graphs & musings

July 14, 2013

6

It’s been a while since I’ve written anything about New Jersey Charter schools, so I figured I throw a few new graphs and tables out there. In the not too distant past, I’ve explained: That Newark charter schools in particular, persist in having an overall cream-skimming effect in Newark, creating demographic advantage for themselves and […]

Rebutting (again) the Persistent Flow of Disinformation on VAM, SGP and Teacher Evaluation

This post is in response to testimony overheard from recent presentations to the New Jersey State Board of Education. For background and more thorough explanations of issues pertaining to the use of Value-added Models and Student Growth Percentiles please see the following two sources: Baker, B.D., Oluwole, J., Green, P.C. III (2013) The legal consequences […]

The Dramatic Retreat from Funding Equity in New Jersey: Evidence from the Census Fiscal Survey

May 30, 2013

8

I have explained in numerous previous posts how New Jersey is among those states that operates a reasonably progressive state school finance system, that New Jersey, throughout the 1990s and early 2000s put the effort into disrupting the relationship between local community income and school spending. And, during that period, New Jersey’s low income students […]

Friday AM Graphs: Just how biased are NJ’s Growth Percentile Measures (school level)?

April 12, 2013

4

New Jersey finally released the data set of its school level growth percentile metrics. I’ve been harping on a few points on this blog this week. SGP data here: http://education.state.nj.us/pr/database.html Enrollment data here: http://www.nj.gov/education/data/enr/enr12/stat_doc.htm First, that the commissioner’s characterization that the growth percentiles necessarily fully take into account student background is a completely bogus and […]

On Misrepresenting (Gates) MET to Advance State Policy Agendas

April 10, 2013

7

In my previous  post I chastised state officials for their blatant mischaracterization of metrics to be employed in teacher evaluation. This raised (in twitter conversation) the issue of the frequent misrepresentation of findings from the Gates Foundation Measures of Effective Teaching Project (or MET). Policymakers frequently invoke the Gates MET findings as providing broad based […]

Who will be held responsible when state officials are factually wrong? On Statistics & Teacher Evaluation

April 10, 2013

34

While I fully understand that state education agencies are fast becoming propaganda machines, I’m increasingly concerned with how far this will go.  Yes, under NCLB, state education agencies concocted completely wrongheaded school classification schemes that had little or nothing to do with actual school quality, and in rare cases, used those policies to enforce substantive […]

Civics 101: School Finance Formulas & the Limits of Executive Authority

March 2, 2013

7

This post addresses a peculiar ongoing power grab in New Jersey involving the state school finance formula. The balance of power between state legislatures and the executive branch varies widely across states, but this New Jersey example may prove illustrative for others as well.  This post may make more sense if you take the time […]

Twisted Truths & Dubious Policies: Comments on the NJDOE/Cerf School Funding Report

December 18, 2012

2

Yesterday, we were blessed with the release of yet another manifesto (as reported here on NJ Spotlight) from what has become the New Jersey Department of Reformy Propaganda.  To be fair, it has become increasingly clear of late, that this is simply the new model for State Education Agencies (see NYSED Propaganda Here), with the […]
