Pre-K Program Evaluation

• Program and student characteristics– Three cohorts were followed through spring 2011– Met minimum income level eligibility– Homeless students = 1.4%– Languages other than English 48% (16 different

languages)Pre-K Cohorts 2007-08 2008-09 2009-10

Pre-K Program Evaluation

• Longitudinal outcomes for district assessments– Pre-K students scored significantly higher on

beginning of year and end of year exams. – Significant findings for subgroups across all exams

include:• Hispanic students (consistently)• English learners (consistently)• African American students (increasing with newer cohorts)

– Pre-K fosters English language development for students and reduces the number identified as English learners in kindergarten.

Pre-K Program Evaluation

• Longitudinal outcomes for STAR testing– Pre-K students outperformed non-Pre-K students

on the Grade 2 CST exams.• ELA 11% more proficient• Math 11% more proficient

– Significant findings for key subgroups include:• African American students• Hispanic students • English learners

Closing the Achievement Gap

• Pre-K program is successful – Across cohorts– Over time– For key subgroups

• CST differences between Pre-K groups are smaller than the differences between the non-Pre-K groups

• Promotes academic readiness• Equalizes early educational vulnerability

• And, we learned much more…….

9

Retention Rates

• As cohorts were tracked over time, analyses of behavior outcomes were also measured.

• For the 2007-08 cohort, retention rates were analyzed.– By second grade, Pre-K participation did not

significantly reduce the overall retention rate of students who had entered kindergarten on time.

– This was very surprising. – Looked further at the African American subgroup

which had shown disproportionate retention rates.

10

Retention Rates

• Further analyses showed:– Pre-K African American students were retained at

the same rate as other ethnicities in the program. – African American students not in Pre-K were

retained at twice the rate of other students.– Only one African American student who was in

Pre-K was retained. – Retention rates were best predicted by early

literacy skill level (literacy component of DRDP).

11

Prelude to Transitional Kindergarten

That Pre-K did not reduce overall retention rates was problematic.

Theory: Children who were not 5 years old near the start of kindergarten might be less developmentally mature and more likely to be retained.

• Compared all age appropriate kindergarten students– “On-time“ (age 5 by August 31) – “Young” (turned 5 between September 1 and December 2)

• Retention rates were higher for the “young” group– A 76% increase in the retention rate – Whereas only 64 “on-time’ students were retained two years later, 49

more students were retained when the “young” group was added. 12

Prelude to Transitional Kindergarten

The Obvious Question: How does Pre-K ameliorate the effect of late birth dates?

• Secondary review of DRDP data for the Pre-K students

• Looked at the differences between “on-time” group and the “young” group

• Results showed that the “young” group: – Had significantly lower pre-test scores on the DRDP– Made greater developmental gains over the course of the Pre-K

program– Had not caught up developmentally to their “on-time” peers.

13

Parent Involvement

• From an achievement gap study, it became apparent that our attendance rate for kindergarteners was much lower than grades 1 or 2 rates.

• The Pre-K evaluation showed that Pre-K students had significantly higher attendance rates than non-Pre-K.

• What was special about this program?

14

Parent Involvement

• Pre-K program requires parental involvement.• Parents MUST bring their children to the program in

order to maintain eligibility.• Children must arrive on time.• Parents who fail to bring their children to school or are

late are visited by a social worker.• The program has parental education components.• Parents are notified of the availability of special

program and services.• Classroom involvement at the Pre-K level is non-

threatening.15

Window of Intervention

• Pre-K study brought to light gaps in our K-12 programs and services.

• Helps us understand the mechanisms of success and pre-cursors to achievement.

• Pre-K data provides a valuable glimpse into early educational issues.

• Provides us with an early opportunity to identify the characteristics of our neediest students and supply appropriate interventions.
