SLN Principals Leading the Way to Improved Scores in New York City
In New York City, where SLN has 5 networks and 135 principals who have participated in SLN programming since 2006, we have been able to correlate improvements in schools and student performance with program participation.
Using the New York City School Progress Report comparing 2008-09 school scores to scores achieved in 2007-08, we analyzed the results for 49 SLN-led schools whose principals have received SLN programming and who have remained at the same school throughout their participation in SLN.
In the Progress Report, each school is compared to its peer group of 40 schools and given a peer horizon score, which can be interpreted as the percentage of the predicted range of scores it covers in that year’s progress report. The range is calculated using peer groups average achievement scores for the three years prior to the progress report. For instance, a value of 50 can be interpreted as a school covering 50% of the weighted range of scores in its peer group.
SLN-Led Schools Outperform K-8 Peer Horizon Schools in English and Math
K -8 Principals who have participated in SLN programming for at least three years have jumped from an average peer horizon score of 46% in 2006-07 to 94% in 2008-09 in English Language Arts (ELA) and from 66% to 90% in Math in the same years. This is 5 percentage points higher in ELA and 8 points higher in math than schools that did not receive SLN programming.
Math Regents Pass Rate Climbs to 85% for SLN High Schools
High schools led by principals receiving SLN programming in 2008-09 had an average peer horizon score in the Math Regents pass rate of 85%, an increase of 25 percentage points from 2007-08.
SLN-Led K-8 Schools Increase Safety Scores Nearly 50%
The average safety score was 77% for SLN-led schools, an increase of almost 50 percentage points since starting programming in 2006-07. These schools had nearly 40 percentage point increases on all other culture indicators, with an average engagement score of 72%, academic expectation score of 60%, and communication score of 65%.
Principals with Three Years of SLN Participation Soar to 95% in Math Scores
High schools led by principals receiving three years of SLN programming increased from 35% to 53% in Math peer horizon scores from 2006-07. Principals receiving two years of programming had an average peer horizon score of 95%, a gain of more than 45 percentage points since 2006-07.
