Academic Achievement - Course Taking , weblink
Analysis of the longitudinal master schedule data collection
Author: Chin-Chih Chen et al Published: Nov 2023

Agency Dataset: Department of Education

This population-based study explored students' participation in advanced coursework in elementary schools (gifted/talented programs), middle schools (Algebra I+), and high schools (Advanced Placement) to address enrollment equity. The study identified demographic disparities and the intersectionality of multiple identities to achieve two research aims: 1) to explore how advanced course-taking varies by student demographics, and 2) to understand how disparities in advanced course-taking vary by student demographics and intersectional identities. The findings indicate that disparities in advanced course-taking are related to students’ race, ethnicity, disability status, English learner (EL) status, socioeconomic status, as well as the intersection of these variables.

Analysis of the longitudinal teacher data
Author: Veronica Katz and Luke C. Miller Published: Apr 2023

Agency Dataset: Department of Education

This study examined how teacher retention and mobility changed after the onset of the COVID-19 pandemic. Teacher same-school retention rates increased to 82.6% following the closure of all schools in March 2020, the highest rate observed over the ten years analyzed, but then dropped to 78.9% following the reopening year (SY 2020-21), the lowest rate observed. The Spring 2021 decrease in teacher retention was due to a substantial increase in teacher departures and a moderate increase in teacher transfers. 10.8% of teachers departed after Spring 2021, and 8.2% of teachers transferred to teach in a different school.

Analysis of the longitudinal PALs test data and social services program participation data
Author: Michah Rothbart and Colleen Heflin Published: Jan 2023

Agency Dataset: Department of Education, Department of Social Services

Using VLDS data, this study focuses on link between social program participation (TANF, SNAP, eligible for free/reduced-price school meals) and literacy and phonological awareness skills, attending to variation between programs and by race/ethnicity. The researchers first compare children in households receiving no, and relatively low, medium, and high support, finding literacy and phonological awareness skills are greatest among children that do not participate in any of the three social programs considered, followed by those who are only eligible for free/reduced-price school meals, and then those who participate in SNAP, and finally those who participate in TANF.


SAT patterns and engineering and computer science college majors: an intersectional, state-level study
College and Career - High School , weblink
Analysis of the longitudinal SAT test data and college enrollment data
Author: Lin Tan et al. Published: Nov 2022

Agency Dataset: Department of Education, State Council of Higher Education

The study investigated the issue of diversity in in engineering and computer science (ECS), fields that pay well and promote upward mobility. Drawing on VLDS data, the findings revealed that within each sex, underrepresented racial/ethnic minority groups (URM) students were at least as likely as their non-URM peers to enroll in ECS programs when they scored within similar SAT score ranges. Students were more likely to enroll in ECS programs if their SAT profile favored math, compared to students with similar math and verbal SAT scores (balanced profile).


A Comparison of Service Time and Racial Categories within Traditional and Alternative Route Internship Programs for Special Education Licensure
Teacher Workforce , weblink
Analysis of the longitudinal special education teacher licensure data
Author: Andrew Wojcik et al., King's College Published: Sep 2022

Agency Dataset: Department of Education

This study used 14 years of state licensure and classroom data from Virginia (via VLDS) to follow 19,878 special education teachers (SETs) who completed either the alternative route (AR) internship or traditional programs. Findings reveal that a greater percentage of SETs of color participated in AR programs compared to traditional licensure programs, while a greater percentage of White SETs completed traditional programs. SETs of color attained approximately three fewer years of service time if they completed the AR program compared to traditional programs. For White SETs, a difference of less than 1 year was found. For SETs from AR programs who did not complete 27 credit hours of university coursework, attrition occurred at higher rates within the first 3 years of service.


Post-Pandemic Onset Public School Student Test-based Performance in Virginia
Academic Achievement - Pandemic , .pdf
Analysis of the longitudinal state assessment data
Author: Luke Miller and Beth Schueler Published: Sep 2022

Agency Dataset: Department of Education

COVID-19 significantly impacted the educational and home environments for students throughout the Commonwealth of Virginia in ways that may have impacted student learning, as measured by standardized exams. This study analyzes statewide, student-level administrative and assessment data on the Standards of Learning (SOL) reading and math tests for the 2011-12 through 2020-21 school years among students enrolled in grades 3 through 8. There was a substantial reduction—a 29% decrease—in the number of 3rd through 8th grade students who took an SOL test in math and reading in the first post-pandemic onset year for which testing data are available (2020-21). Among test-takers, pass rates declined by 32% in math between the last full pre-pandemic year (2018-19) and the first post-pandemic onset year (2020-21), and by 4% in reading.


Post-Pandemic Onset Public School Student Enrollment and Mobility in Virginia
Pandemic - Student Enrollment Pandemic , .pdf
Analysis of the longitudinal student enrollment data
Author: Beth Schueler and Luke Miller Published: Aug 2022

Agency Dataset: Department of Education

The disruptions caused by the COVID-19 pandemic likely impacted families' decisions about whether and where to enroll their children in public schools. The study used longitudinal student enrollment data to track individual students over time throughout the Commonwealth of Virginia to highlight how enrollment changed during the first full school year after the onset of the COVID-19 pandemic. Statewide enrollment in pre-kindergarten through grade 12 dropped by four percent (53,830 students) between the pre-pandemic fall of 2019 and the first post-pandemic onset fall of 2020. Enrollment drops occurred in most grade levels but were concentrated in pre-kindergarten and kindergarten. The largest enrollment declines were among White students and students who were not economically disadvantaged.


Virginia High School Graduates' Career and Technical Education Credentials: Top Credentials over Time and across Student Groups
CTE - Diploma , .pdf
Analysis of the longitudinal student graduation data
Author: Julie Harris, Deborah Jonas, and Rebecca Schmidt Published: Jan 2021

Agency Dataset: Department of Education

Starting in 2017, the Virginia Department of Education (VDOE) began requiring students graduating with the Standard diploma to earn a career and technical education (CTE) credential to encourage them to pursue opportunities that enhance their career readiness. This study examined the CTE credentials Virginia high school graduates most commonly earned, and hoe they align to a specific occupation or industry.


Illuminating inequality in access: Variation in enrollment in undergraduate engineering programs across Virginia's high schools
College and Career - High School , weblink
Analysis of the longitudinal high school graduates and college enrollment data
Author: David Knight et al. Published: Oct 2020

Agency Dataset: Department of Education

This study uses a dataset from the Virginia Longitudinal Data System that includes all students who completed high school from a Virginia public school from 2007 to 2014 (N = 685,429). The findings illuminate inequality in enrollment in engineering programs at four-year institutions across high schools by gender, race, and socioeconomic status (and the intersections among those demographics). Different high schools have different engineering enrollment rates among students who attend four-year postsecondary institutions.
