Community Impact


The SEAL model expanded to 65 California schools this 2015-2016 school year—more than 39,000 students in Santa Clara, San Mateo, Alameda, Marin, and Los Angeles counties are being reached by this effective, powerful model of language learning.


“The SEAL model has been deeply effective in preparing students for academic success, by developing the high-level cognitive, language and literacy skills that are integral to the Common Core State Standards. SEAL is proving both replicable and sustainable—and our School Board sees its value.

Jan Christensen, Redwood City School District Superintendent


SEAL 5-Year Pilot Evaluation Summary


An evaluation of the Model’s impact on students and family literacy practices during the five-year pilot was conducted by Dr. Kathryn Lindholm-Leary, Professor Emeritus of the College of Education at San Jose State University and nationally recognized researcher on dual language education. Dr. Lindholm-Leary focused on the first three full cohorts of Spanish-speaking English learner participants at three schools—Hoover Elementary in Redwood City School District, and Almaden and Gardner Elementary schools in San Jose Unified School District.


Each student that was enrolled in a SEAL preschool classroom was followed longitudinally as he or she progressed through the grade levels. Using three different assessment measures, including standard assessments relied upon by school districts and the state, the evaluation analyzed each student’s growth in language development and academic achievement.


Outcome data were available on a total of 265 students who received “Full” SEAL treatment (i.e. attended SEAL preschool) across three cohorts: 91 children in Cohort 1, 97 children in Cohort 2, and 77 children in Cohort 3. In addition, there were 310 students who received “Partial” SEAL (i.e. SEAL in elementary grades but did not attend the SEAL preschool): 92 in Cohort 1, 112 in Cohort 2, and 106 in Cohort 3.


Despite starting school with language and academic skills behind their peers, SEAL students catch up or surpass peers on all measures. Major findings show statistically significant gains in language, literacy and cognition, as well as a significant impact on family literacy. Specifically:

  • 76% of students scored within the highest two level overall categories of language and literacy development on the DRDP
  • A great majority of the students were at grade-level expectation by the end of SEAL preschool in mathematics (82%) and cognitive (77%) development as measured by the DRDP
  • SEAL students gained an average of 18 points of the PreLAS over a two year period (preschool and Kindergarten)
  • 85% of SEAL students early advanced or advanced on CELDT by entry into 4th grade
  • 54% scored proficient or advanced on CST (English) Mathematics
  • 65% scored proficient or advanced on STS (Spanish) Mathematics

In addition, SEAL students tended to show equal or higher levels of growth and achievement in language, literacy, and mathematics achievement than comparison students. By third grade, students receiving Bilingual instruction scored similarly or higher than students receiving English instruction on the CELDT, the California Standards Test (CST) in both language arts and math, and the Standards Test in Spanish in both language arts and math.


And SEAL has a significant impact on parents and literacy activities in the home. SEAL students come from homes with very low incomes ($27,384 per family of 4) and very low parent education levels (87% with high school or less). Half of SEAL parents read books with their child on a daily basis, and engage regularly in literacy-related activities.


SEAL Replication Evaluation


This fall we are launching an external evaluation of SEAL Replication. Given its comprehensive nature, we will be collaborating with multiple organizations—one of our evaluation partners is Loyola Marymount University’s Center for Equity for English Learners (CEEL).

Evaluation is anticipated to include:

  • Information on student impact and growth, changes in teacher practices, information on systemic change, data on the development of family/school partnerships, and an analysis of SEAL implementation
  • At least a 3-year timeline for data collection, with both formative and summative analyses
  • Representative sampling of SEAL students (estimated between 7,000-10,000)
  • Several measures used during the pilot evaluation, along with new measures related to CAASP and the OPAL (validated classroom observation tool developed by CEEL at LMU)

Award Winning Program


For 35 years, the California School Board Association [CSBA] has honored educational programs that exemplify highly effective governance, teaching, and student learning through its Golden Bell Award program. In November 2014, SEAL at Hoover Elementary School was chosen as best in class in CSBA’s brand new “Common Core” category. After a rigorous review of the model by a 26-member panel of education experts that included on-site validation and assessment, SEAL at Hoover was recognized for fully aligning curriculum, instruction, and assessments, along with providing cutting-edge professional development and building effective collaboration between all stakeholders, to successfully implement Common Core State Standards in Hoover classrooms—with particularly impressive outcomes for English Learners.

SEAL at Hoover also received the California Association of Bilingual Education (CABE) 2015 Seal of Excellence Award. CABE applauded the Hoover School administrative leadership, their dedicated teachers and strong community who had the courage and vision to join the SEAL model and transform their school into an effective, powerful model of language learning for all students.
