To promote academic excellence in our high schools, we created the Excellence Index (EI): a simple way of rating schools academically by focusing exclusively on high achievement. The EI quantifies the percentage of students scoring at the highest levels on an array of exams. Scores are referenced to state and global norms, which are set to a EI score of 75 (representing a typical level of high achievement). To get a 75 score based on last school year’s test score data a school would have:
– 13% score a 5 on AP exams
– 10% score in the 90 percentile or higher on the SAT
– 9% score Distinguished Learner (Level 4) on EOCs (average of all 8 subjects)
– 29% score 6 or 7 on IB exams (if applicable)
These are each weighted equally in the index.
New Manchester High School’s Excellence Index score for 2018 is 14. This means that New Manchester students were about 5 times less likely to score at the highest levels on exams than their peers statewide or nationally. The underlying data is in the graph below:
This data shows that New Manchester students were 10 times less likely to score in the 90% on the SAT; 13 times less likely to score a 5 on any AP exam, and 3 times less likely to score Distinguished Learner on the EOC.
NMHS’s previous EI score was a 10. The increase of 4 points is due to:
1. An increase from 0% to 1% (representing 2 students) scoring in the 90 percentile on the SAT.
2. The decline in the state Distinguished Learner rate on EOCs (used as a reference point) from 9.6 to 9, increased its EI points in the EOC category.
If you are a stakeholder at New Manchester High School (e.g. parent, grandparent, homeowner in the district, future parent), please help us advocate for excellence by contacting Principal Marco Holland to express concern over these results and ask exactly what is being done to raise more students to these levels of achievement:
