Review: Student Learning Growth
To comply with state law, the FLDOE chose a value-added 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 range.
To receive a rating of Effective, Any Point in the Confidence Interval must
intersect at any point with the range.
To receive a rating of Needs Improvement, the Upper Bound of the Confidence
Interval must be located in .
To receive a rating of Unsatisfactory, the Entire Confidence Interval must be
located in the 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.
Because this employee’s entire confidence interval touches no category other than ‘Highly Effective’ at any point, this employee is rated as ‘Highly Effective’.

You can select the graph icon in the new column on your 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.
