“REACH” Rating Calculator for Teachers/Counselors/Librarians/Clinicians on an Annual Cycle
(If you are on the two-year evaluation cycle, you will not get a rating until the end of SY 2014-15)
If you are on an annual evaluation cycle and did not have four observations, CPS is unable to rate you.
See Article 39-2.4 (p. 139), “Inability to Rate or to Provide Rating”. If you are a PAT (Probationary
Appointed Teacher=untenured) without four observations this school year, you will be issued a
Proficient rating. If you are a tenured educator without four observations this school year, your most
recent rating will be treated as your current rating.
For all educators on the annual cycle this year, CPS says that they will post a summary of your
observation scores to RLS by mid-July. That summary will give you your Teacher Practice Score, which
will range from 1-4. It is easy to use this information to get an estimate of what your rating will be.
Here is the Scoring Range Table for the final summative rating you will receive in August/September
2014 (Article 39-2.5, p. 140):
Unsatisfactory
Developing
Proficient
Excellent
Minimum
100
210
285
340
Maximum
209
284
339
400
Once you know your Teacher Practice Score, you can calculate your estimated final summative rating:
Step 1. Multiply your Teacher Practice Score by 75 if you are an elementary or high school teacher or
librarian, or by 100 if you are a clinician or counselor. The number you get when you multiply your
Teacher Practice Score by 75 or 100 is your Known Point Total.
If you are a clinician or counselor, you have no “student growth” points to worry about. Look up your
Known Point Total on the Scoring Range Table and determine your estimated final summative rating.
Step 2. If you are an elementary or high school teacher or librarian, add 25 points to your Known Point
Total. Twenty-five points is the lowest possible score that you could receive for Student Growth. Look
up this new total (Known Point Total + 25) on the Scoring Range Table to determine your lowest possible
estimated final summative rating.
Step 3. Now, go back to your original Known Point Total and add 100 points. One hundred points is the
highest possible score that you could receive for Student Growth. Look up this new total (Known Point
Total + 100) on the Scoring Range Table to determine your highest possible estimated final summative
rating.
Most teachers will receive neither the highest nor the lowest number of Student Growth Points. If you
assume that your Student Growth Points will fall somewhere between about 50 and 75, you can further
refine your estimated final summative rating.

If you do not know your Teacher Practice Score, you can:
 wait for CPS to upload your Teacher Practice Score around the middle of July, and then calculate
your estimated rating by following the steps on page 1.
 use the steps below to calculate your Teacher Practice Score first, and then calculate your
estimated rating by following the steps on page 1.
 ask CTU for help in calculating your Teacher Practice Score (Contact: CarolCaref@ctulocal1.com)
If you want to calculate your Teacher Practice Score yourself and you have received scores for all of
your four required observations as well as scores for Components 4b-4e, follow the steps below.
1. Start by averaging all of the component scores for each observation, using 1 for Unsatisfactory,
2 for Basic, 3 for Proficient, and 4 for Distinguished. You can use the table below to help
organize your calculations. You won’t have four scores for Domains 1 or Component 4b, unless
all of your observations were formal. It is possible you won’t have four scores for each
component in Domains 2 and 3 because evaluators do not have to score every component for
Informal Observations. You should average whatever component scores you did receive across
each component. There will only be one score for each of the Components 4b-4e. You don’t
need to write anything in the grey cells. An example is included on page 5.

2. Next, average the Domain Totals and multiply each Domain Total by the Domain Weights shown
below and then add together each “Domain Average times Domain Weight”. An example is
included on pages 5-6.

The “Sum of Domain Weighted Averages” will be the same as the Teacher Practice Score described on

final summative rating.

If you have Performance Task information and know both the Beginning of Year (BOY) and End of Year
(EOY) Rubric Scores for the student scores you submitted in CIM, then you can calculate your
Performance Task Score.
1) Using the group you submitted in CIM with both BOY and EOY scores, count the number of
students who either increased their rubric score from BOY to EOY or started and ended with a
score of 3.
2) Divide that number by the total number of students in the group you submitted in CIM with
both BOY and EOY scores.
3) Multiply the result of the division in 2), by 100.
4) Divide the answer from 3) by 33.
5) Add 1 to the answer in 4).
6) Multiply the answer in 4) by 10 or 15. If you are a 3-8 elementary teacher who teaches
Reading/ELA or Mathematics, or a high school teacher of Mathematics, English Language Arts,
or Science, multiply by 10. If you are a K-2 teacher, a 3-8 teacher who does not teach
Reading/ELA or Math, or a high school teacher who does not teach Math, ELA, or Science,
multiply by 15. That is your Performance Task Score.
7) Your Known Point Total is now your Teacher Practice Score + Performance Task Score. If you
used 10 as the multiplier in 6), you have 15 to 60 unknown points. If you used 15 as the
multiplier in 6), you have 10 to 40 unknown points. You can use the Scoring Range Table to
estimate what your summative rating will be.
Performance Task Scoring EXAMPLE:
1) I have 17 students who grew or stayed at rubric level 3
2) I submitted 25 students for Performance Task scoring in CIM, so (17/25) is the fraction of
students who grew
3) (17/25) * 100 = 68
4) 68/33 = 2.06 (rounded to two decimal places)
5) 2.06 + 1 = 3.06
6) I teach 6th grade science, so I multiply by 15.
3.06 * 15 = 45.9
7) Let’s say my Teacher Practice Score is 228. Add that to the Performance Task Score of 45.9,
for a Known Point Total of 273.9. I know that the least amount of points left that I can get
(for VAM) is 10, and the least total points I can have is 283.9. Therefore, according to the
Scoring Range Table, I am likely to have a Proficient Summative Rating, assuming I am a
couple of points above the minimum of 10 VAM points available. On the other hand, it is
possible to get a Developing, and I cannot get an Excellent rating, because the most number
of VAM points I can get is 40, and that is not enough to bring my total up to 340.

If you are a tenured teacher who had two formal observations, your observation scores might

For each Component, the Average is calculated by adding together each observation score and
then dividing by the number of scores.
(From the example table above: The Component 1a Average= 2 (Obs 1) + 3 (Obs 3) = 5/2=2.5)
Each Domain Total then is calculated by adding together all of the “Averages of each
Component”.
EXAMPLE:
Using Domain 1 from above as an example, the Domain 1 Total is divided by 5 because there are
five components in Domain 1. The resulting number is the Average of Domain 1. This Average is
then multiplied by the Domain Weight (25%) in order to get the Domain 1 portion of your
Teacher Practice Score. Repeat this process for each Domain.

Once you have calculated the “Domain Average times Domain Weight” for each of the four
Domains, add them together and then you have the “Sum of Domain Weighted Averages” which
is your Teacher Practice Score.
