Statewide assessment · North Carolina & Arizona

Reading and mathematics achievement, grades 3–8

Through the National Center on Assessment and Accountability for Special Education (NCAASE), Dr. Nedim Yel worked directly with student-level statewide achievement test data from North Carolina and Arizona in reading and mathematics for grades 3–8.

NCAASE studied achievement growth and assessment accountability for students with and without disabilities using longitudinal state assessment data.

Mapping California’s digital divide during COVID-19

As Senior Data Scientist at the California Department of Education and a Strategic Data Project Fellow, Dr. Nedim Yel geocoded nearly four million student addresses using R and combined FCC broadband and Ookla network data in QGIS to examine potential connectivity gaps.

He explored multiple routes to usable evidence, including a school-specific connectivity survey. Changes to student information systems would take 18–24 months, while voluntary survey participation would leave gaps.

Decision supported: A geographic starting point for state leaders addressing the digital divide. Mapped availability did not establish household subscriptions or reliable service.

Understanding Connecticut educators’ experiences during and after COVID-19

Dr. Nedim Yel is a coauthor, credited as a consultant, of a June 2026 report from the Center for Connecticut Education Research Collaboration, a partnership between the Connecticut State Department of Education and higher education institutions.

The Part 1 report draws on 1,093 teacher survey responses and interviews with teachers and administrators in six districts to examine changes in practice, sources of strain, and support. Survey analyses include descriptive and inferential statistics and ordinal logistic regression.

Decision supported: Recommendations for district and state leaders on educator support, professional learning, and the pace of new initiatives. Findings describe six purposively selected districts and are not statewide estimates.

Indiana courts: Accessing Justice with Zoom

Dr. Nedim Yel is a coauthor, affiliated with DASS, of the 2023 Indiana University report Accessing Justice with Zoom. The study analyzed responses from 1,878 unrepresented court users, with research conducted across 40 courts in 12 Indiana counties.

He managed, cleaned, and prepared court data, conducted the analysis, and contributed to report writing.

When a ready-to-use data export was unavailable, he developed a court-authorized scraping workflow to collect the relevant case records and prepare them for analysis.

A proposed engagement structure

Know what is due.
Know when to expect it.

Each proposal defines the questions, deliverables, responsibilities, and review dates before work begins.

01 /

Kickoff

Confirm the decision, reporting requirements, available data, and project responsibilities.

02 /

Evaluation plan

Agree on measures, analysis methods, data access, and the deliverable schedule.

03 /

Interim findings

Review early results and data limitations before the final reporting stage.

04 /

Final report

Receive findings, methods, limitations, and a presentation or handoff as scoped.

Proposed fee approach: Phased, not-to-exceed fees with defined deliverables. Pricing and dates assume client-supplied data in the agreed format by the agreed date. Additional preparation, delayed data, or scope changes are addressed through an agreed change order. Final terms are set in the proposal.

Data access and reporting

Plan the work around your environment.

DASS can work within a client's approved system or remote desktop environment. Access arrangements and data-handling responsibilities are agreed for each engagement.

  • Client-approved accessDefine where data is accessed, who has permission, and which outputs may be exported.
  • Student-data requirementsDiscuss your FERPA-related requirements and required data-sharing agreements during scoping.
  • Documented methodsSpecify code, documentation, and reproducibility deliverables in the proposal.
Survey & assessment shortening

Shorter surveys.
Defensible measurement.

Survey fatigue uses up participant time and staff capacity. Explore whether a shorter instrument can preserve the measurement quality your reporting needs.

How it works

Item response theory helps examine which items contribute useful measurement information. A proposed short form needs validation for its intended population and use. Reliability and score agreement must be evaluated before replacing an existing instrument.

Your statistical lead

Methods expertise.
Direct collaboration.

Dr. Nedim Yel

PhD with a specialization in Measurement, Statistics, and Methodological Studies.

Work directly with a statistician to connect the evaluation questions, available data, and reporting requirements.

Practical problem-solving: When data or systems fall short, evaluate the alternatives against scale, privacy, and operational constraints, then build a feasible path to useful evidence.
