What is the Cohort Graduation Rate? • New formula required by the federal government to calculate graduation rates • 2008-09 cohort is made up of the students who first entered high school in 2005-06 • Adjusted for students who move into or out of the system, emigrate to another country, or are deceased
Change from Previous Years • In the past, graduation rates were based on the NCES formula • National Center for Education Statistics (NCES)– • One year snapshot • Did not include students who receive a modified diploma, GED, adult high school diploma, or alternative certificate in the calculation • Looked at all graduates in a given year, regardless of number of years in school. • Cohort – • Follows a four year group (or cohort) of students • Students who receive a modified diploma, GED, adult high school diploma, or alternative certificate are counted as non-graduates • Looks at students who graduate within four years • ODE has received approval for a five-year cohort rate for next year
Why is the Cohort Rate Lower? • Factors that lower the cohort rate: • Inclusion of students who receive a modified diploma, GED, adult high school diploma, or alternative certificate as non-graduates • Counting only those who graduate within 4 years
If a school has a 65% cohort grad rate does this mean 35% of their students are dropouts? No. While the remaining 35% does include dropouts, this percentage also includes students who received a GED certificate; received an adult high school diploma from a community college; students who are enrolled in an alternative school; or students still enrolled and taking longer than four years to graduate.
Why Change to this Rate and Why Now? • Federal requirement for all states starting with 2011-12 AYP report • A more uniform and accurate measure of high school graduation which allows us to clearly see where each student is ending up after 4 years in high school • Producing a cohort rate requires a longitudinal data system to follow students through high school. ODE has been working with school districts since 2004 to build this data system • The Class of 2009 is the first set of students that we can follow from their eighth grade year through four years of high school
Accountability • For this transitional year, ODE has produced both a cohort graduation rate and a NCES graduation rate • For this year, schools that do not meet federal AYP graduation requirements based on their cohort graduation rate, may meet on their NCES rate • Next year ODE will not produce the NCES rate • ODE will produce both a four-year and five-year cohort rate next year
Comparing to Other States Can Oregon’s cohort formula be compared to other state’s cohort formulas? • Not this year as states are still in various stages of implementation • e.g. some states do not currently require their special education students to meet cohort graduation targets. • In 2011-12, the cohort graduation rate will be the common standard used by every state and there will be a higher degree of comparability
Dropout Rates • The calculation of dropout rates has not changed from previous years and is not impacted by the changes in the graduation rate calculation • A dropout is defined as an individual who has withdrawn from school and has not received a regular diploma, modified diploma, extended diploma, alternative certificate, or GED • The NCES dropout rate is the number of students who drop out of school (grades 9-12) in a given year divided by the total number of students enrolled that year
