Overview

The CSDE is committed to continuously learning from data and experience to implement evidence-based educational policies and practices that result in improved student outcomes. The CSDE’s learning agenda is guided by the State Board of Education’s four promises to Connecticut’s students:

  1. Ensuring their non-academic needs are met so they are healthy, happy, and ready to learn. (Mental health, nutrition, after-school programs)
  2. Supporting their school and district in staying on target with learning goals.(Education Cost Sharing - ECS, Alliance Districts, Commissioner’s Network, School Choice)
  3. Giving them access to great teachers and school leaders.
  4. Making sure they learn what they need to know to succeed in college, career, and life.

    English Learners

    • Demographic Trends of Connecticut’s English Learners (SY 2015-16 to 2019-20)  English Learners are a heterogeneous group of students, reflecting diverse languages, racial and ethnic backgrounds, cultures, socio-economic statuses and other characteristics. It is the civil right of English learners to receive language supports as a part of their core programming and accessibility supports embedded in their core grade-level academic content. This report examines the diverse characteristics of Connecticut’s English Learners such as immigrant and special education statuses, native languages spoken, their grade distribution and language program participation. It also highlights significant trends and changes they have experienced from SYs 2015-15 through 2019-20.
    • A Closer Look at Connecticut’s High School English Learners (SY 2018-19)  English learners (ELs) are a subgroup of Connecticut’s high school students, unique from their non-EL peers in the challenge they face to access and master secondary-level academic content while concurrently trying to develop English language proficiency. Additionally, they are also sometimes distinguished from non-EL peers by their demographic characteristics. This paper presents a statewide picture of high school ELs in SY 2018-19, including their demographics, assessment results and trends in these areas.
    • Academic Growth on the Mastery Examination of English Learners in Bilingual Education Programs (2017) This report presents the first results of the academic growth of English learners in bilingual education programs. The traditional approach to evaluating academic performance has been to report academic achievement. However, achievement is a snapshot measurement where the students evaluated are often different from one year to the next. Therefore, this report focuses on the growth or change in achievement of the same students from one year to the next i.e., from 2014-15 to 2015-16 on Connecticut's Smarter Balanced growth model.

The CTAS has been developed to ensure that all students with significant cognitive disabilities can participate in an assessment that is a measure of what they know and can do in relation to the Next Generation Science Standards (NGSS). This report describes the standard setting activity that was conducted with Connecticut educators to establish performance standards (cut scores) for the CTAS assessment.
     
  • Validating American Institutes for Research’s Calibration and Scoring Processes for Science Assessments (2019)Introduction of new three-dimensional science standards have ushered in innovative methods for assessing students’ knowledge of science. New psychometric models were needed to account for the fact that item-level scores are clustered due to a common stimulus. Connecticut's vendor for science assessments, the American Institutes for Research, has had to rely on software that was developed in-house to calibrate and score these assessments. State level data quality control checks could not be accomplished through commercially available psychometric software. This paper summarizes a series of studies conducted by the Connecticut State Department of Education to validate AIR’s calibration and scoring processes. Partner: University of Connecticut

    • Studies in Progress

    The following studies are in progress:

  • How do social emotional learning data gathered from student surveys as well as early reading assessments administered in Grades K through 2, improve the prediction of student proficiency on the Smarter Balanced ELA assessment in Grade 3? Partner: Meriden Public Schools
  • What is the relationship between student participation in the Smarter Balanced interim assessment blocks and their performance on the corresponding assessment target on the summative assessment?
  • How effective are evidence-based text messaging campaigns in reducing “summer melt” and improving enrollment persistence in Connecticut so that students are more successful in completing their postsecondary education? Partners: American Institutes for Research, Connecticut State Colleges and Universities
  • What is the relationship between the number of years a student attends a particular school and the amount of growth that is achieved on Connecticut’s Smarter Balanced growth model in Grades 4 through 8?
  • What are the long-term educational outcomes of children with and at-risk for developing reading and writing difficulties? What are the antecedents in the schooling process of children who later develop reading and/or writing disabilities? Partner: University of Houston
  • What should be Connecticut’s operational definition of college and career readiness (e.g., first year college GPA, # of credits earned in first two years, self-sufficiency wage)? What factors in high school (e.g., high school course work, test scores, attendance, mobility, discipline, grade repetition) best predict college and career readiness? Partners: P20WIN members including CSCU, UCONN, CT Conference of Independent College, DOL (see P20WIN data request)
  • How can student performance and persistence in middle school serve to predict potential for participating in rigorous coursework (e.g., advanced placement, international baccalaureate, dual enrollment) during high school
  • How does the long-term academic achievement of former English learners who participated in bilingual education programs (transitional and/or dual language programs) compare to that of other former ELs who received ESL instruction?
  • What is the relationship between a parent’s participation in adult education programming and their child’s outcome in school?
  • Student Participation in Distance Learning: Device/Connectivity Needs, Effective Strategies, Challenges, and State Supports Needed - On behalf of the Learn from Home Task Force (LHTF), the Connecticut State Department of Education (CSDE) conducted a brief survey to gauge the approaches to distance learning during the COVID-19 pandemic, including the extent of student participation in those offerings and the barriers (especially devices and connectivity) to greater participation. In addition, the survey sought district perspectives on effective strategies to increase student participation in distance learning, the most challenging areas for getting fuller student participation, and the specific supports the State of Connecticut can provide to increase student participation in distance learning. 
  • The Roles of Race, Ethnicity, Gender, and Mental Health in Predicting Truancy Recidivism - This study aims to (a) describe demographic and mental health (MH) differences between truant juvenile justice–involved youth (JJY) and nontruant JJY; (b) classify MH needs of truant JJY; and (c) investigate if the interactions between race, ethnicity, gender, and MH needs predict truancy recidivism. Participants were 10,603 truant JJY (55.4% male; non-Hispanic White, 46.8%; 16.2% with a history of pretrial detention). Of these participants, 2,167 with MH data were included in latent profile analyses and recidivism analyses. Hispanic youth and female youth were more likely to be truant. Non-Hispanic White JJY had a higher likelihood of a repeated truancy charge. Four MH classes emerged: elevated Alcohol/Drug Use (7.9%), elevated Angry–Irritable and Depressed–Anxious symptoms (19.5%), elevated Suicide Ideation (7.1%), and low MH needs (65.5%). Race, ethnicity, gender, and MH needs are informative as potential factors contributing to truancy. These factors should be examined in future studies that compare truant with nontruant non-JJY.
