For legal & public-policy research

Your evidence needs to survive a court, a legislature, or an agency review.
We've designed studies built for exactly that.

Empirical legal studies, field experiments, and rigorous policy evaluation — including a statewide legal-needs assessment projected to save ≈$2M in research costs, and a national center evaluating how states measure accountability.

We had an unrealistically tight timeline, and Dr. Yel jumped in without hesitation — not only met the deadline, but delivered a little earlier than we anticipated. He took the time to understand the situation behind the data and the implications of every insight. We know who to go to for future work like this.

DASS did a fantastic job. They were patient, clear about the coding, and very responsive to my emails. They took the time to understand the overall goal before proceeding with each step. Highly recommend.
