The subject of this post is extremely critical to teachers and principals in our public schools. The new laws connecting teacher evaluation directly to layoff, salary, and tenure should require that any evaluation system be as accurate as possible. But it seems like our
education hierarchy at the state level comprised as it is of rank
amateurs, is destined to make one blunder after another. I believe the evidence presented below demonstrates that the Value Added Model portion of the teacher evaluation system now being implemented by LDOE contains serious flaws that can unfairly destroy the careers of many good teachers and principals.
I mentioned in one of my recent emails
that there was ample evidence coming directly from Dr George Noell
(the father of VAM in Louisiana) that the value added model is
erratic and unreliable in measuring good and bad teaching. Today
I would like to discuss with you the clear evidence for this conclusion.
Wayne Free, Director of Instruction and
Professional Development for the Louisiana Association of Educators
has just written an extremely good analysis of Louisiana's Value
Added Model. From this analysis we can easily conclude that the
Louisiana VAM should never be used to evaluate the performance of
teachers, should not be used to deternine the order of lay off of teachers, for freezing
a teacher's salary, or for removing tenure and placing teachers on a
path to be fired. Yet despite all the evidence I am about to present
here, all of these actions that are so destructive to the teaching
profession and to the education of our children will soon start
happening. Please
click on this link to the LAE website for Mr Free's
analysis. For this post I will just summarize one of the most
critical findings in his study.
The most damning evidence that this VAM
is far from ready for prime time comes from several answers to
direct questions posed by Mr Free to Dr Noel. Here is the most
outstanding one:
Free asked: "What percentage of the
teachers rated in the bottom 10% by the VAM in one year would be
expected to be rated again as ineffective the following year if
they did nothing to change their teaching from one year to the next?"
( The following is my comment) I believe that if this system is
accurate in identifying ineffective teachers, the answer would be
somewhat close to 100%, especially if the system is considered
reliable enough to destroy a teacher's career. Right? ... Wrong!)
The percentage possibility of a repeat
of an ineffective rating in the succeeding year according to Noell is
only 26.8%. And that is assuming the teacher does not change his/her teaching. This was shocking to me. The fact that there is only a
one in four chance of the same result the following year means that
the system is erratic and may have incorrectly identified
large numbers of teachers as being ineffective in the first place. It
means that contrary to the assumption in the legislation, that the
process will be deliberative and free of gross errors, such teachers
will immediately be placed first in line for layoff, have their
salaries frozen, and those rated ineffective next year will
permanently lose their tenure and be placed on a path to dismissal. But the most damaging result of such
an incorrect determination I fear, is that the local newspapers will
somehow get the list of the teachers rated as ineffective and publish
it in the home town paper where a teacher's reputation will be
permanently destroyed and parents will be demanding that their
children not be assigned to that teacher's class. This could easily
happen this year to a teacher with 20+ years experience and a
previously perfect evaluation record!
One of the most unfair requirements of
the evaluation system, is that even if a teacher gets a great
evaluation on the qualitative (Compass) from her/his principal, but gets
an ineffective rating on VAM (quantitative) the final result is
required to be
an automatic overall ineffective rating.
This rule is in direct violation of Act 54 which states that VAM is
supposed to make up 50% of the overall result. (not 100%) This is
sure to result in numerous lawsuits. I suggest that all teachers
vulnerable to VAM join their teacher association/union now so that
their lawsuits can be funded if necessary.
A perfect example of how crazy the
results can be is the strange outcome reported in an
editorial published recently by the Lake Charles American Press. The American
Press editors were appalled by the fact that the VAM system is set up
to find 10% of all teachers evaluated as ineffective no matter how
well or how poorly they actually perform. This is called grading on
the curve, and is not allowed in any public classroom. We measure and
grade our students by how well they master the material. If 80 or 90
percent of the students master the material, that many will get an A
or a B, and if no student fails, then that is something we celebrate. Not
so with the teacher evaluation system. It has been
predetermined that
a minimum of 10% of our teachers
must fail. The
American Press editors say that such a system borders on being
immoral!
But it gets worse. The editors found
that for some strange reason, in the pilot program that was run
recently by LDOE, one of the best performing school systems in the
state (Jeff Davis) had only 3 percent of its teachers rated as highly
effective, and a disproportionately high percentage rated as
ineffective. In fact several of the highest performing districts in
the Lake Charles area had some of the lowest teacher VAM scores. How can that
be? This system is both illogical and destructive!
See the editorial in the American Press. Not only are teacher evaluations adversely affected by this tendency, but their principal's evaluations could also be damaged because of the number of "ineffective" teachers in their school.
The Baton Rouge Advocate carried a story recently about the teachers of a high
performing school in Shreveport also getting disproportionately low
VAM scores in the pilot program. Our amateur Superintendent White is
quoted as characterizing this as an isolated glitch which can easily be
corrected. Maybe his 12,000 per month (part time) PR person can
somehow spin this fiasco as a positive.
What's worse, as is implied by White in
the Shreveport situation, the LDOE managers of VAM can
change the complicated formulas that produce the value added results
at will without consulting anyone. So they can manipulate the
results. They are probably doing just that as this post is
being written and you and I have no way of knowing. I wonder what
group of teachers will be penalized next time after the formula has
been tweaked to take care of Shreveport? And your professional career
depends on this foolishness?
For more information on flaws in VAM in general as it is used in several other states you may want to read an
analysis by Gary Rubinstein. Thanks to Cathy, one of our readers for suggesting this link.
If you as as outraged by this as I am,
would you please send an email to your legislator, who can easily
change this in the next legislative session before it affects anyone.
In my last post I gave you a
link to the legislative ID system that
gives you email addresses of your legislators. I know many of you
meant to send emails at my last request but you may have been too
busy. I know how busy you are but this is critical!
Here is a sample email:
Dear
(insert your legislator name), The most recent information available
about the new Act 54 evaluation system clearly shows that it is an
unreliable system for rating teacher performance. I hope you agree
with me that the stakes are too high and that professional educators
should not be rated by a system that is flawed. Please take whatever
steps necessary to stop this evaluation system immediately
and not implement it or any other evaluation system until it is
proven reliable. Thank you for supporting your professional educators
in this critical matter.
Signed: ____.
There is one more thing I am asking you
to do right now. If you have not already done so, submit your contact
data to me so you can become a part of my Defenders of Public
Education data base. The educators, school board members and parents
in this data base will receive timely notices of upcoming actions at
BESE and the legislature so you can contact your representatives
before they vote. Believe me all of us together can make a
difference! Just send me an email at
louisianaeducator@gmail.com
with your home address
or if you prefer send me the
district numbers for your representative and senator (it will save me
the trouble of looking them up). Include your preferred email
address so that my emails can reach you anytime your help is needed.
Believe me we can change this is
we just stick together and speak as one!
Thanks again for all you do as an
educator or parent or school board member. We can never thank you too
much for your valuable contribution to public education.
