Question and Answer
Review: Student Learning Growth


To comply with state law, the FLDOE chose a valueadded model to measure a teacher’s contribution to
student learning
This model accounts for some of the key variables
that influence student learning including prior test
scores, attendance, mobility, ESE and ELL status, and
class size.
Review: Student Learning Growth



The FLDOE model produces in a score and standard
error that is individualized for every teacher and
unique for every school.
The standard error is based on the number of
students taught and the consistency of student
results.
The standard error is a measure of the degree of
variation that is likely in the score.
Review: Student Learning Growth


The standard error can be used to create a confidence
interval (range of scores) that take into account the
potential error in any score.
The larger the adjustment for standard error used, the
more confidence that the range of scores created is an
accurate reflection of teacher or school influence on
student learning.
0.5 Standard Error ~ 38% confidence
 1.0 Standard Error ~ 68% confidence
 2.0 Standard Error ~ 95% confidence

The FLDOE provides districts
with a file containing
information on teacher Student
Learning Growth (SLG) scores.
Though much more data are
available than presented, some
scores are personal and some
scores are school scores.
Through recommendations of
the Teacher Evaluation
Committee, the Principal
Evaluation Committee,
teachers, principals, and other
district staff, we chose a
calculation method that uses
this data as fairly and
equitably as possible.
Student Learning Growth Calculation


Classification decisions are made based on the entire confidence interval calculated.
To receive a rating of Highly Effective, the Entire Confidence Interval must be located
in the the
Highly Effective range.
To receive a rating of Effective, Any Point in the Confidence Interval must intersect at any
point with the Effective range.
To receive a rating of Needs Improvement, the Upper Bound of the Confidence Interval must
be located in Needs Improvement .
To receive a rating of Unsatisfactory, the Entire Confidence Interval must be located in the
Unsatisfactory range.

The SLG score and standard error is used to create a confidence interval for each person or
school that displays with 95% confidence a range of scores. The data from the entire interval is
used to make classification decisions. The data for the employee presented above is graphed
below. The SLG score is represented by the circle and the lines extending out from the circle
represent the confidence interval.

evaluation table
to find the
confidence
interval used for
the SLG score
classification.
Student Learning Growth Details
When you select the graph icon in
the new column in your evaluation
table, a file will appear that
presents your score, your standard
error, and your confidence interval.
Please remember that some
personnel received scores directly
calculated from students they instruct
and other personnel received scores
calculated from their associated
school(s).
Student Learning Growth Details Examples



We are going to examine a few examples of the
student learning growth details.
The student learning growth details chart will provide
your name, evaluation year, student learning growth
rating, score, standard error, and a graphical
representation of your confidence interval.
Please note that the confidence interval is not drawn to
scale but meant to represent how the classification
decision was made.
Frequently Asked Questions



Why do I have the same evaluation score (e.g. 3) as
another person who also received an individual
score?
