New Numbers for N.J.'s Data-Driven Teacher Evaluations

John Mooney has the break-down on the new proportions of SGP's (Student Growth Percentiles) that will be used for teacher evaluations. These lower values are the result of a compromise between the Christie and NJEA, articulated in  Christie's Executive Order, which gradually amps up the use of data to assess classroom effectiveness. The Order also includes more leeway on SGO's, or Student Growth Objectives.

Here are the numbers from NJ Spotlight:

 Evaluation of teachers of 4th - 8th grade language arts and math  in 2014-2015:

    10 percent median student growth percentiles (SGPs)

    20 percent student growth objectives (SGOs)

    70 percent teacher practice through classroom observation

Evaluations of all other teachers will consist of:

    20 percent student growth objectives

    80 percent teacher practice

Evaluations of teachers  4th - 8th grade language arts and math in 2015-2016:

    Up to 20 percent median student growth percentile (as determined by DOE)

    20 percent student growth objectives

    60 percent teacher practice

Evaluations of all other teachers will consist of:

    20 percent student growth objectives

    80 percent teacher practice
