ONE DISTRICT WIDE APPROACH FOR THE STUDENT PERFORMANCE CATEGORY

District-wide Group Metric Option for The Student Performance Category

Summary
This district SLO score would be calculated based on the percentage of students meeting or exceeding the target score on all Regents exams plus the 4th grade and 8th grade Science exams.

Target Setting
The target is calculated based on the performance for the previous three-year period on an exam-by-exam basis. The first step is to determine the anchor point, or what exam score at least 80% of the students met or exceeded for each of the previous three years.

For example:
Algebra Common Core Assessment:
•	2013- 81% of all valid exam scores met or exceeded a score of 49
•	2014- 82% of all valid exam scores met or exceeded a score of 47
•	2015- 82% of all valid exam scores met or exceeded a score of 47

The next step is to determine the Anchor Point Average by calculating the average of the exam anchor points from the previous step.  Returning to our example, (49+47+47)/3=47.6
Exam	Anchor Point	
2013 Algebra CC	49	
2014 Algebra CC	47	
2015 Algebra CC	47	
Anchor Point Average	47.6	

As the district SLO score is based on a growth methodology, the target score must exceed the three-year average of the anchor scores. Therefore, the final target score will exceed the Anchor Point Average by 1 point.

In our example, this would calculate to be 47.6 + 1= 48.6 rounded up to a 49.

The process outlined above is then repeated for each assessment, creating a target score for each exam.

Exam	2016 Target Score	
Common Core Algebra	49	
Common Core Geometry	44	
Trigonometry/Algebra 2	43	
Common Core English	49	
U.S. History & Government	51	
Global History & Geography	43	
Chemistry	53	
Earth Science	49	
Living Environment	48	
Physics	51	
4th Grade Science	49	
8th Grade Science	36	

Percent of Students Meeting Target
To determine the SLO scoring range and HEDI Rating, the number of students meeting the target must be determined first. This will be based on the total number of valid exam scores during the course of the same reporting year, (Regents from August, January, and June) compared to the target score identified for each exam.

Exam	2016 Target Score	Exam Scores Meeting/Exceeding Target	
Common Core Algebra	49	2,564	
Common Core Geometry	44	875	
Trigonometry/Algebra 2	43	628	
Common Core English	49	1,697	
U.S. History & Government	51	1,158	
Global History & Geography	43	1,982	
Chemistry	53	221	
Earth Science	49	659	
Living Environment	48	1,893	
Physics	51	93	
4th Grade Science	49	1,100	
8th Grade Science	36	676	

This can now be compared to the number of valid exams to determine an overall percentage. In our example 13,546 exams met or exceeded the target score out of a possible 17,464 exams. This yields a final average of 77.565% rounded to 78%.

Exam	2016 Target Score	Meeting/Exceeding Target	Total Exams

Common Core Geometry	44	875	1,202	
Trigonometry/Algebra 2	43	628	784	
Common Core English	49	1,697	2,071	
U.S. History & Government	51	1,158	1,512	
Global History & Geography	43	1,982	2,543	
Chemistry	53	221	269	
Earth Science	49	659	821	
Living Environment	48	1,893	2,233	
Physics	51	93	129	
4th Grade Science	49	1,100	1,432	
8th Grade Science	36	676	1,005	
Total Percentage=77.565%	13,546	17,464	

Determining the Final HEDI Rating
Once the total percentage has been determined, this percentage will then be compared to the state provided chart to determine the final rating.  In our example, 78% meeting the target yields a score range of 15 and a final HEDI Rating of Effective.
