Previously, we looked at
Lynn public school attrition rates. Here we look at two other statistics regarding school enrollment: the
intake rate and
stability rate. The
intake rate
measures the number of students that enroll in the state, a district, or school
after the beginning of the school year (generally after October 1st in a given school year). The
stability rate measures how many
students remain in a district or school throughout the entire school year as measured through a comparison of October 1st and end of school year enrollment information.
Below is the intake and stability rate information for the Lynn public school district and KIPP Academy Lynn Charter School for the 2011-12 school year.

At the individual school level, stability rates across all public schools in Lynn (including KIPP) were relatively similar with the exception of Fecteau-Leary Junior/Senior High which had the lowest stability rate in the city at 56%.

The Massachusetts Department of Elementary and Secondary Education also reports stability rates at the subgroup level.

Lynn Public School Intake Rates 2012
In considering both the stability and intake rates as well as the attrition rate, one has to consider the implications these statistics has achievement for public schools in Lynn. Having a large percentage of students or even a specific population of students both enrolling and transferring out of a school or district at any point in the year and/or after the school has the potential to have a negative impact on the school or district's overall achievement in terms of standardized testing and other academic indicators.
Below are the stability, intake and attrition rates for Lynn elementary schools along with their accountability rankings; Level 3 and 4 schools have been highlighted in blue. Accountability rankings are as follows:
- Level 1: On track to college and career readiness
- Level 2: Not meeting gap closing goals
- Level 3: Focus: Lowest performing 20% of schools (including schools with the largest gaps)
- Level 4: Priority: Lowest performing schools
- Level 5: Priority: Chronically under-performing schools

Here we see that Level 4 Harrington, for example, has a 89.5% stability rate and a 21.3% attrition. This coupled with the 16.4% intake rate suggests that Harrington's student enrollment sees considerable changes throughout the school year and from year to year. In thinking school achievement, consideration must be made of pertinent mobility related statistics (stability, intake and attrition) in addition to other factors order to have an accurate picture of the school or district's overall achievement, student population and the challenges that the school or district may be facing.
