B ALTIMORE C ITY P UBLIC S CHOOLS B ALTIMORE C ITY P UBLIC S CHOOLS Teacher Evaluation Update Given the transition in state assessments, recent legislation (i.e. former Senate Bill 676) prohibits the use of state assessments for teacher and principal evaluation until City Schools will not use student growth measures in the teacher evaluation that will be used for compensation because all of the measures we planned to use include state assessment data. Teachers will experience the full evaluation (i.e. professional practice and student growth measures) through the use of a formative report for developmental purposes. 2

B ALTIMORE C ITY P UBLIC S CHOOLS Calculating the Scoring Ranges (Cut Scores) As an example, to set the “Highly Effective” scoring range you would start with 3.5 because 3.5 rounds up to 4, which is the highest score available using the Instructional Framework rubric. Then you would multiply by 25 to put the score on a 100-point scale. Then you would multiply by.85 to assign the weight of 85% for classroom observations.  Step 1: 3.5 x 25 = 87.5  Step 2: 87.5 x.85 =

The composite evaluation rating, as well as the ratings on any of the measures, will be used to determine professional development opportunities for teachers to target strengths and weaknesses. Performance improvement plans can still be written based on the composite evaluation rating, any single evaluation component, or for any reason. They do not have a direct impact on compensation. 14
