1. New York State Education Department Using Growth Measures for Educator Evaluation
August 2012

2. By the End of This Presentation….
You should be able to:
Explain how growth ratings (HEDI) and scores will be obtained from educator overall MGPs and confidence ranges based on State-provided growth measures

3. Evaluating Educator Effectiveness 2011-12
Student growth on state assessments (state-provided)
Student learning objectives
Growth
20%
Student growth or achievement
Options selected through collective bargaining
Locally Selected Measures
Rubrics
Sources of evidence: observations, visits, surveys, etc.
Other Measures
60%

4. Key Points about NYS Growth Measures
We are measuring student growth and not achievement
Allow teachers to achieve high ratings regardless of incoming levels of achievement of their students
We are measuring growth compared to similar students
Similar students: Up to three years of the same prior achievement, three student-level characteristics (economic disadvantage, SWD, and ELL status)
Every educator has a fair chance to demonstrate effectiveness on these measures regardless of the composition of his/her class or school.

5. Review of Terms SGP (student growth percentile): Similar students:
the result of a statistical model that calculates each student’s change in achievement between two or more points in time on a State assessment or other comparable measure and compares each student’s performance to that of similarly achieving students
Similar students:
students with the similar prior test scores,(up to three years), and ELL, SWD, and economic disadvantage status
Unadjusted and adjusted MGP (mean growth percentile):
the average of the student growth percentiles attributed to a given educator
For evaluation purposes, the overall adjusted MGP is used. This is the MGP that includes all a teacher or principal’s students and takes into account student demographics.

6. MGPs and Statistical Confidence87
Lower Limit
Upper Limit
Confidence Range
NYSED will provide a 95% confidence range, meaning we can be 95% confident that an educator’s “true” MGP lies within that range. Upper and lower limits of MGPs will also be provided.
An educator’s confidence range depends on a number of factors, including the number of student scores included in his or her MGP and the variability of student performance in the classroom.

7. Growth Ratings and Score Ranges 2011-12
Description
Growth Score Range
(2011–12)
Highly Effective
Well above state average for similar students
18–20
Effective
Results meet state average for similar students
9–17
Developing
Below state average for similar students
3–8
Ineffective
Well below state average for similar students
0–2
The growth scores and ratings are based on an educator’s combined MGP.

8. HEDI Classification Approach: Teachers and Principals
Highly Effective (Well Above Average) requires:
An educator’s MGP is greater than 1.5 standard deviations above the State mean.
For this means MGP’s greater than or equal to 69 for teachers.
Effective (Average) requires:
An educator’s MGP is between 1 standard deviation below the State mean and 1.5 standard deviations above the State mean.
For , MGPs of 42 through 68 for teachers.
Developing (Below Average) requires:
An educator’s MGP is between 1 and 1.5 standard deviations below the State mean.
For , MGPs of 36 through 41 for teachers.
Ineffective (Well Below Average) requires:
An educator’s MGP is more than 1.5 standard deviations below the State mean.
For this means MGPs less than or equal to 35 for teachers.

9. From MGPs to Growth Ratings: Teachers Rules on last slide result in these HEDI criteria for 2011-12
Yes No
Is your MGP ≥ 69?
Is your Lower Limit > Mean of 52?
Highly Effective: Results are well above state average for similar students
Is your MGP ≤ 35?
Is your Upper Limit < 44?
Ineffective:
Results are well below state average for similar students
Developing:
Results are below state average for similar students
Effective:
Results equal state average for similar students
