Late on August 31, the NJDOE released a statement that there would be a change in the weight of median student growth percentile (mSGP) scores for teachers of tested subjects for the 2016-17 school year. Returning to the 2013-2014 school year’s weights, the mSGP score will account for 30% of a teacher’s summative evaluation. Student Growth Objective (SGO) scores will continue to account for 15% of the evaluation for teachers in both tested and non-tested subjects.
The scores used to calculate the mSGP score will be the scores that students earn during the 2016 – 2017 administration of PARCC, which will be administered during the spring of 2017. These mSGP scores will be received during the 2017-18 school year. The summative ratings that teachers with an mSGP receive sometime this winter will be for the 2015-16 school year and will count for only 10% of the teacher’s summative rating.
History of the mSGP
In 2013-14, the first year of implementation of TEACHNJ, the mSGP score accounted for 30% of the summative ratings for teachers of tested subjects, 4th through 8th grade language arts and math. The score was based on the NJASK, which was then the state administered test.
Largely because of concerns raised by NJEA, when the state transitioned to the PARCC for the 2015-16 school year, the mSGP score was reduced to 10% for 4th through 8th grade teachers of language arts literacy and 4th through 7th grade math. Because some 8th grade students take Algebra rather than an integrated Math course, they take the Algebra end of course exam, so the NJDOE decided to not include mSGP for 8th grade teachers of math.
Now that the state has administered the PARCC for two years, the NJDOE has announced the intention to move the percentage of mSGP scores back to the original 30%. This change comes at a time when the newly passed Elementary and Secondary Education Act has reduced the pressure from the federal government and has called for more flexibility on the use of test scores for teacher evaluation.
August 31st was the last possible date for a change in the mSGP percentage. In mid-August, the NJDOE sent out a “Back to School” AchieveNJ memo and made no mention of a possible change in the mSGP percentage.
NJEA has condemned this increase as being out of touch with the needs of students in New Jersey.
