Data Analysis

Agora Education Research provides advanced data analysis for both quantitative and qualitative education studies, ensuring accurate and meaningful insights for programs and policymaking at the national, state, and local levels.
Our multidisciplinary team of statisticians, psychometricians, and social scientists specializes in cleaning, organizing, and analyzing complex data from large-scale surveys and assessments. We use statistical techniques such as descriptive statistics and predictive modeling to translate raw data into actionable knowledge and psychometric analysis such as item response theory (IRT) to ensure reliability and validity of instruments..
Our team also performs qualitative analysis of data from in-depth interviews, cognitive interviews, focus groups, open-ended survey responses, observations, and textual documents. Our analytical approaches include content analysis, narrative analysis, discourse analysis, thematic analysis, and grounded theory to identify patterns and themes, to help clients to understand complex human perceptions and behaviors, and to inform strategic decisions and policy formulation.

Alka Arora, Ph.D.
Associate
Dr. Alka Arora is a researcher and psychometrician with more than 25 years of experience in K–12 STEM assessment, measurement, and data analysis across the major national and international studies, including the National Assessment of Educational Progress (NAEP), the Trends in International Mathematics and Science Study (TIMSS) and TIMSS Advanced, and the Program for International Student Assessment (PISA). Her work centers on the content and framework side of large-scale assessment — assessment design, framework and standards-alignment studies, item and scoring-guide review, and the cross-assessment comparisons that allow NCES to interpret and report U.S. results in an international context. She brings particular depth in mathematics and science content, constructed-response scoring, and standard-setting.
Most recently, Dr. Arora spent more than a decade as a Senior Researcher at the American Institutes for Research (AIR), supporting the NAEP assessment development program through development plans, assessment design, item and framework review, and small-scale investigations to support assessment quality, alongside reviews of NAEP results, snapshots, and state and TUDA reporting. She conducted multiple framework and item comparisons among TIMSS, NAEP, and PISA to identify how the assessments’ constructs align and differ, and served as lead mathematics content expert for the 2023 Maryland College and Career Readiness Empirical Study. Earlier, over nearly a decade at Boston College’s TIMSS & PIRLS International Study Center — as Researcher, TIMSS Advanced Project Coordinator, and Assistant Research Director — she coordinated the development of TIMSS, TIMSS Advanced, and TIMSS Numeracy frameworks, achievement tests, background questionnaires, and scoring rubrics, and served as a liaison among study directors, participating countries, and the international research community.
Dr. Arora holds a Ph.D. in Educational Research, Measurement, and Evaluation from Boston College and began her career as a secondary STEM teacher. She is a certified Project Management Professional (PMP) and a certified reviewer under the What Works Clearinghouse 5.0 group-design standards, and is a member of AERA, the National Council of Teachers of Mathematics, and the Comparative and International Education Society. Her published scholarship includes work on student misconceptions in physics and mathematics drawn from TIMSS data and a comparison of the Next Generation Science Standards with the NAEP frameworks.

I’m a Researcher with over two decades of experience designing, implementing, and analyzing large-scale education assessments. My work focuses on uncovering meaningful patterns in student learning—across countries, cultures, and contexts—through rigorous data collection and thoughtful analysis.
At the American Institutes for Research (AIR), I collaborated with federal agencies and partner organizations on the U.S. implementation of PISA, a global assessment of student literacy conducted in over 80 countries. This experience deepened my understanding of how school systems and cultural factors shape educational outcomes, and strengthened my ability to translate complex data into practical, evidence-based takeaways. I’ve led technical reviews, managed sensitive student data, and supported the development of high-quality publications under tight deadlines. Beyond analysis, I’ve guided dissemination efforts through in-depth statistical reports, tailored presentations, media briefings, and practitioner-friendly briefs. I also spearheaded the RISE webinar series, which highlights global education research and encouraged dialogue across policy, practice, and research communities.
I’ve always loved the mix of precision, analysis, and people in my work—whether I’m refining survey tools, exploring complex datasets, or mentoring junior staff. I care deeply about making data clear and useful, and I bring empathy and attention to detail to every aspect of the process. Years of remote collaboration have also sharpened my ability to stay organized, meet tight deadlines, and stay connected across teams and time zones.
I’ve seen how much we can learn from different education systems—whether across countries or across states—by comparing student and school-level factors like motivation, instructional methods, and learning environments. Rigorously designed assessments don’t just measure what students know; they help us understand how students learn and grow. I’m committed to using research to shape smarter education policies and create more equitable opportunities for all learners.
