Studies pertaining to the effectiveness of NBPTS-certified teachers are ongoing. Here is a partial list.

Advanced Teacher Certification
http://www.education-consumers.com/Cunningham-Stone.pdf
Evidence that there is any educationally meaningful advantage to certification by the National Board for Professional Teaching Standards is still lacking.  [Cunningham, G. K. & Stone, J. E. (2005).

In the face of growing concerns about the cost of awarding a $7,500/year bonus to teachers certified by the National Board for Professional Teaching Standards, a legislatively mandated study by the South Carolina Department of Education found that NBPTS-certified teachers were having little impact on student achievement.  [Michals, L.  (2005, December 21).  Teacher credentials get little credit.  The State (Columbia, SC).]

https://caldercenter.org/publications/effects-nbpts-certified-teachers-student-achievement  [released March 2007] An NBPTS-sponsored study of learning outcomes for all Florida teachers over a 4 year span.  Found limited evidence favoring NBPTS-certified teachers but concludes that the “efficacy of NBPTS as a tool to improve student learning appears questionable.”  [Harris, D. N. & Sass, T. R.  (2007, January 25). The effects of NBPTS-certified teachers on student achievement.  Working Paper No. 4, Urban Institute, Center for the Analysis of Longitudinal Data in Educational Research.]

https://dc.statelibrary.sc.gov/bitstream/handle/10827/5836/GOV_Executive_Budget_2007-2008.pdf?sequence=1&isAllowed=y [released January 3, 2007] South Carolina Governor Mark Stanford’s budget message cites the lack of supporting evidence and $63.17 million/year projected cost as the basis for discontinuation of bonuses for NBPTS teachers newly certified after June 30, 2007 (see page 99).

http://www.education-consumers.com/articles/W-M%20NBPTS%20certified%20report.pdf

http://www.education-consumers.com/articles/South%20Carolina%20NBPTS%20report.pdf
[released November 20, 2005]  Study commissioned by South Carolina legislature found achievement gains associated with NBPTS-certification little different than average.  [Fisher, S. & Dickenson, T.  (2005, November 11).  A Study of the Relationship Between the National Board Certification Status of Teachers and Students Achievement, Columbia, SC: Office of Program Evaluation, College of Education, University of South Carolina.]

http://www.education-consumers.com/Cunningham-Stone.pdf
A review and critical analysis of 4 studies that examined the link between NBPTS-certification and student achievement gain.  Found that reports of statistically significant gains were misleading.   Concludes that effective teaching is far more accurately identified on the basis of value-added achievement gains alone.  [Cunningham, G. K. & Stone, J. E. (2005). Value-added assessment of teacher quality as an alternative to the National Board for Professional Teaching Standards: What recent studies say. In Robert Lissitz (Ed.). Value added models in education: Theory and applications.Maple Grove, MN: JAM Press. ]

(2004, April 27). Can teacher quality be effectively assessed? Urban Institute.]

https://eric.ed.gov/?id=ED472132 [released May 5, 2002] Found that 16 out of 16 NBPTS-certified teachers in Tennessee produced only average value-added student achievement gains.  A scholarly panel commissioned by the Education Commission of the States and headed by Susan Fuhrman, President of Teachers College, Columbia University reviewed the findings and urged that they be disregarded.  [Stone, J. E. (2002, May 1). The value-added achievement gains of NBPTS-certified teachers in Tennessee: A brief report. College of Education, East Tennessee State University.]

Brain-based Learning
https://www.aft.org/ae/summer2005/willingham Concludes that the popular notion that student achievement is maximized when teaching is fitted to the child’s preferred cognitive modality is false.  [Willingham, D. T. (2005, Summer).  Ask the cognitive scientist.  American Educator]

Class Size
http://www.psychologicalscience.org/journals/pspi/pdf/pspi2_1.pdf
“Overall, the weight of the evidence tilts strongly toward a conclusion that reducing class size, by itself, does not typically affect the instructional activities that occur in classrooms.”  Teacher behavior changes are far more important.  [Ehrenberg, R.G., Brewer, D.J., Gamoran, A., & Wilms, J.D. (2001). Class size and student achievement. Psychological Science in the Public Interest, 2(1).]

Project STAR Technical Report 
The complete report of the widely-cited class size study funded by the Tennessee General Assembly in the 1980s. Contrary to many abbreviated versions of the report, the findings do not make a strong case for reduced class size as a means to school improvement.

Evidence from Project STAR
Article by Project Star’s principal investigator concludes that across-the-board class size reductions are an expensive way to make modest improvements in school outcomes.

Reading
https://journals.sagepub.com/doi/10.1111/1529-1006.00004
The failure of schools to systematically teach decoding skills is probably the greatest single reason for children not learning to read.  [Rayner, K., Foorman, B.R., Perfetti, E., Pesetsky, D., & Seidenberg, Mark S. (2001). How psychological science informs the teaching of reading. Psychological Science in the Public Interest, 2(2).]

Research Quality
https://ies.ed.gov/ncee/wwc/
“The What Works Clearinghouse (WWC) was established in 2002 by the U.S. Department of Education’s Institute of Education Sciences (IES) to provide educators, policymakers, researchers, and the public with a central and trusted source of scientific evidence of what works in education.”  It gathers and summarizes research but does not endorse particular interventions.  The Education Consumers ClearingHouse endeavors to base its recommendations on WWC findings as they become available.

https://www.psychologicalscience.org/observer/when-research-findings-and-social-norms-collide
Social, behavioral, and educational findings that are seen as undermining support for a particular policy, program, or legislative initiative, or as potentially minimizing the significance of particular problems are subject to subtle publication restrictions.  [Ricciuti, H.  (2005).  When research findings and social norms collide,
a look at the role of public policy in research reporting.  APS Observer, 18(7).]

https://www.jsonline.com/
“Yogi Berra wisdom on educational research,” an article in the June 29, 2008 edition of the Milwaukee Journal Sentinel highlighting the ease with which valid research is ignored in favor of approaches more attuned to the philosophies of educators.

Results of Education Reform
https://fordhaminstitute.org/
In a press release dated October 19, 2005, the Thomas Fordham Foundation observed that the gains in reading scores evidenced on state assessments have not been corroborated by the 2005 National Assessment of Education Progress.   Instead, it appears that the state standards have grown more lax.

Smaller Schools

The Bill and Melinda Gates Foundation has invested $1 billion in an initiative to reduce school size.  So far, it has been a “learning experience.”  [Geballe, B.  (2005, July 12).  Bill Gates’ Guinea Pigs. Seattle Weekly.]

Schooling Costs
https://www.heartland.org/publications-resources/publications/education-in-oklahoma-the-real-costs
When generally accepted accounting principles are used to calculate per-pupil costs, public schools are receiving substantially greater funding than is generally understood.   [Anderson, S. J. & Dutcher, B.  (2005).  Education in Oklahoma: The real costs.  Oklahoma City, OK:  Oklahoma Council of Public Affairs.

Self-Esteem
https://journals.sagepub.com/doi/10.1111/1529-1006.01431
For 30 years, teachers have been taught that elevated student self-esteem was a primary prerequisite to learning success.   As it turns out, the experts had it backwards:  Success in school and elsewhere brings about higher self-esteem.  Students who are encouraged to work hard and behave themselves are better served than ones taught to merely think well of themselves.  [Roy F. Baumeister, R. F., Campbell, J. D., Krueger, J. I., & Vohs, K. D.  (2003).  Does high self-esteem cause better performance, interpersonal success, happiness, or healthier lifestyles?  Psychological Science in the Public Interest, 4(1).]

Student Effort
http://www.psychologicalscience.org/journals/index.cfm?journal=ps&content=ps/archive
Self disciplined effort and the ability to put work before pleasure predicts school success better than IQ.  [Duckworth, A. L. and Seligman, M. E. P.  (2005).  Self-Discipline outdoes IQ in predicting academic performance of adolescents.  Psychological Science, 16(12).]

http://www.aaeteachers.org/newsletters/augustnews04.pdf
“Teachers have been expected to be stimulating but not obtrusive, challenging but not demanding of overexertion. They have been told that if their teaching is truly enthusiastic, innovative, and creative, students will learn spontaneously, if not effortlessly.”  In truth, “learning takes study, and study takes time and effort.”  A student work ethic is essential to educational success.  [Stone, J. E.  (2004 August).  Learning requires more than play.  Education Matters, 10(7).]

Teaching Practices

https://www.air.org/resource/csrq-center-report-elementary-school-comprehensive-school-reform-models
The American Institutes for Research has undertaken a review of 22 of the most popular comprehensive school reform models.  Direct Instruction (one of the least popular models among teacher-educators) and Success For All were the most strongly supported by evidence of effectiveness.  Direct Instruction’s success corroborates the findings of the very large scale Follow Through study reported in 1976.  In contrast, several of the models that incorporate so called “best practice” teaching methodologies were supported by little or no evidence. [Comprehensive School Reform Quality Center (2005, November).  CRSQ Center report on elementary school comprehensive school reform models.   Washington, DC: American Institutes for Research.]

https://www.chronicle.com/article/we-dont-need-that-kind-of-attitude/
Teacher training programs have been requiring prospective teachers to adopt “politically correct” views (i.e., dispositions) on matters such as equity, diversity, and social justice.  Now the National Council for the Accreditation of Teacher Education says their standards have been wrongly interpreted.  [Wilson, R. (2005, December 16).  ‘We don’t need that kind of attitude.’  Chronicle of Higher Education, 52(17).]

http://www.educationation.org/wakawaka.htm
If you have never experienced a teacher education course, you must see these pictures.  They were taken by a professor walking around the halls on his college campus.  Displays of this type are typical projects for teachers taking certain elementary education courses.  Semester grades are usually based on the appearance of the display and a 30-minute class presentation by the student.

http://www.edweek.org/ew/articles/2005/06/22/41aera.h24.html
After 4 years of sifting through the available research, a 766 page study by the American Educational Research Association found little empirical evidence to support claims of effectiveness for widely used teacher training practices.  These findings are consistent with an earlier and heatedly disputed review of the teacher training literature by the Abell Foundation {insert this link:  http://www.abell.org/pubsitems/ed_cert_1101.pdf}.  [Videro, D.  (2005, June 22).  Review panel turns up little evidence to back up teacher ed. practices.  Education Week, 24(41).]

What Teachers Have to Say About Teacher Education 
The complaints of teachers in this 1996 survey focus on the same facets of teacher-training that were reflected in “Different Drummers,” a 1997 Public Agenda survey of teacher-education professors. “The greatest weakness of the courses offered in teacher education programs, according to survey responses, is that they are so enamored of theory they are of no practical use.”
