National Policy Context

Secretary Spellings’ “Bright Lines” and Flexibility

• Tennessee and North Carolina were pilots for growth model based on school year 2005-06 data, both continued for year 2

• Information from pilots will guide reauthorization of the Elementary and Secondary Education Act in 2007

Basic Facts about Current AYP Model and the Growth Model Pilots

• Current AYP Model• Annual proficiency targets for reading

and math for all schools and districts for grades 3 – 8 and high school

• Safe harbor provision gives credit to schools and districts that fail reaching the proficiency target when they can show that they have a 10% or more reduction in the students that tested below proficient from the previous year.

Basic Facts about Current AYP Model and the Growth Model Pilots

• Growth models for accountability• At the time of enactment of NCLB, a few

states had growth model accountability systems which held their schools and districts responsible for growth in individual student academic progress.

• These models measured a student’s “growth” in an academic area by comparing test scores on the current year test to previous years.

• Tennessee’s “value-added” growth model was one of these.

Benefits of a Growth Model

• More accurate picture of a school’s effectiveness because it measures the impact of its educational programs on individual students’ growth instead of comparing different cohorts of students from one year to the next as the current safe harbor does.

Benefits of a Growth Model

• More accurate picture of schools with:• Small numbers of students• Large numbers of students who enter

their first grade already academically behind

• Large numbers of mobile students

Benefits of a Growth Model

• Data which can better inform instruction and services

• Strong potential to encourage schools to maximize ALL students’ progress, not just to focus on moving “bubble” students from below proficient to proficient.

• Build “reward” system around growth instead of status model.

AYP Growth Model

• Elementary/middle schools have two ways to meet AYP proficiency targets:• Status/safe harbor model• Growth model

• Growth model uses a student’s projected score on an assessment three years into the future• not value-added

AYP Growth Model

STATUS GROWTH

3rd grade current score

4th grade current score 7th grade projected score

5th grade current score 8th grade projected score

6th–8th grade current score HS EOC projected score

Students new to state current score

Students who take alt. assessment current score

AYP Growth Model

• Students with projected scores that fall above the proficiency standard are counted as proficient

AYP Growth Model

• Students with projected scores that fall below the proficiency standard are counted as below proficient

AYP Growth Model

• Students who are currently below proficient but have projected scores at the proficient or advanced level are counted as proficient

• Students who are currently proficient or advanced but have projected scores at the below proficient level are counted as below proficient

Projection Example

AYP Growth Model

• TN set a very high standard to meet AYP through the growth model

• All subgroups must meet the AYP target

• In both reading/language arts and math

First-Year Results

• 7 schools met the requirements of the growth model – and therefore met AYP overall

Conclusion

• The AYP growth model holds great promise to• Help states identify the schools in

greatest need of assistance• Encourage schools to focus on all

students, including those in greatest need of assistance
