About Jean

Jean Knab has expertise in research design and implementation, evaluation technical assistance, and systematic reviews. Her experience covers a range of policy areas, including teenage pregnancy prevention, education, early childhood, and support for low-income families.

Knab is the project director of a $7.2 million project for the U.S. Department of Health and Human Services, Office of Adolescent Health (OAH) overseeing more than 60 grantees and local evaluators conducting rigorous studies of programs designed to reduce risky sexual behaviors and pregnancy among teens. The project provides grantees and evaluators with training and technical assistance to ensure quality evaluations are designed, implemented, analyzed, and disseminated. Knab is also the deputy project director on a multi-site design and feasibility study of teen pregnancy prevention programs for OAH. She will co-lead the project and design of four evaluations, oversee site selection and monitoring, and summarize final results. Knab is also a researcher on the evaluation of the Personal Responsibility Education Program, a large-scale initiative to replicate evidenced-based pregnancy prevention programs nationwide, overseeing an impact evaluation in New York. Previously Knab oversaw reviewer certification training and topic area reviews on the What Works Clearinghouse. Knab also directed a project to help a foundation determine whether it is achieving its goal of reducing hardships and poverty through the administration of small grants to individuals and families.

Before joining Mathematica, Knab served as the study director for the Fragile Families and Child Well-Being Study, a longitudinal study of a birth cohort of youth, focused largely on understanding the effects of being born to unmarried parents. She also worked at MDRC on numerous welfare to work evaluations. A reviewer for several academic journals, including Demography and the Journal of Marriage and Family, she holds a Ph.D. in sociology, with a concentration in demography, from Princeton University.

    To continue to build the evidence base on teen pregnancy prevention, a federally funded cohort of 2010-2015 Teen Pregnancy Prevention grantees are conducting independent, rigorous evaluations of their programs. Mathematica is providing evaluation technical assistance to ensure design and implementation...

  • Personal Responsibility Education Program (PREP)

    To help reduce the risks of pregnancy, sexually transmitted infections, and associated risk behaviors among teenagers, Congress authorized PREP as part of the 2010 ACA.
