2011 – 2012: Application of Assessment Data for ALL Classroom <strong>Teacher</strong>s<br />
The following procedures will be applied for ALL classroom teachers:<br />
The district will use the student performance data from the 2011‐2012 assessment processes provided<br />
by FLDOE that is tied to the identified FCAT Subject/Grade level <strong>Teacher</strong>’s students. Using the Value<br />
Added Model (VAM) data provided by FLDOE, an Aggregated <strong>Teacher</strong> VAM score will be calculated<br />
using the formula below:<br />
<br />
<br />
<br />
This Aggregated <strong>Teacher</strong> VAM score is calculated by dividing the current year VAM score assigned to<br />
the teacher by the absolute value of the average of three years of consecutive VAM scores. Using the<br />
absolute value of the average teacher VAM score will maintain the positive or negative magnitude of<br />
the ratio based on the current teacher VAM score. The Aggregated <strong>Teacher</strong> VAM will be applied to the<br />
Student Performance Data Table as listed below and will account for 50.3% of the overall teacher<br />
evaluation rating. Revisions to this evaluation model will be ongoing as new data is obtained from<br />
district assessments and FLDOE.<br />
