• Calculating Evaluation Ratings

    For most principals, the 2016-17 School Leader Effectiveness Evaluation end of year rating will be determined by a composite score made up of individual scores from components in each of the two categories of effectiveness being measured. When performance data is available for all components in the School Leader Effectiveness Evaluation, the “professional practice” and “student growth” components each account for 50-percent of a principal’s overall evaluation and include the following weighted measures:   

    SY 2016-17 Measures of School Leader Effectiveness

    *Principals who did not write a SY 15-16 HSA-aligned SLO for scoring and inclusion in this year's annual evaluation will have a SY 16-17 SLO that is weighted at 35% of their total evaluation. 

    These individual ratings (raw score) are converted to a 100-point scale, weighted and combined to yield a single overall composite rating. This overall annual rating is based on where a principal’s School Leader Effectiveness Composite Score is within the annual evaluation score ranges. For the 2016-17 school year, the School Leader Effectiveness Evaluation annual evaluation score ranges remain consistent with the 2015-16 school year. Specifically:

    City Schools will be using the following rating calculations for the 2016-17 School Leader Effectiveness Evaluation. To generate this rating, City Schools follows a four-step process that you can see in the following example: 

    (For more information on calculating your annual evaluation, please review this 1-page overview guide.)

    Note: Consistent since the 2014-15 school year, annual evaluations for principals with missing performance data from one or more evaluation components will be reweighted. Missing performance data is when data is not available, and are not the same as scenarios where a school leader fails to complete his or her responsibilities in the evaluation process.

    School leader's raw score

    Explanation

    Leadership Framework

    3

    All indicators within a core value (on a scale of 1-4) are averaged together.  Then all 4 core values (on a scale of 1-4) are averaged together to form an overall composite rating on the Leadership Framework.

    360 Feedback Survey

    4

    This school leader’s final average from the 360 Feedback Survey includes ratings from teachers, supervisors and a self-assessment, on a scale of 1 to 5. Each respondent average is averaged together to calculate the final average.

    SY 16-17 Student Learning Objectives

     85

     Student Learning Objectives are specific, measurable academic goals for a particular group of students in an academic year. Completed SLOs are scored on a scale of 54 to 100.

    SY 15-16 HSA-aligned SLO

    77  Completed SLOs are scored on a scale of 54 to 100.

    School Performance Measure

    60

    The SPM consists of multiple quantitative indicators that reflect a whole school’s year-long performance in terms of student growth and the extent to which the school’s learning environment is conducive to student growth. This measure is scored on a 100-point scale

     Explanation

    25

     75
    (3 x 25)

    Because the Leadership Framework is on a 4-point scale, a multiplier of 25 is used to place the score on a 100-point scale

    360 Feedback Survey

    4

    20

     80
    (4 x 20)

    Because the 360 Feedback Survey is on a 5-point scale, a multiplier of 20 is used to place the score on a 100-point scale
