For education researchers

Federal-grade methods for federally funded research.
We've done it at scale.

Study design, multilevel modeling, and reporting for IES-, NSF-, and foundation-funded education research — drawing on our team's roles in projects with total awards exceeding $15M. These figures describe project funding, not consulting fees.

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.

I recruited Nedim for his analytical skills and research abilities. He brought very strong quantitative research skills and the interpersonal ability to work effectively with a wide range of people from diverse backgrounds. He excelled at ferreting out and interpreting information from multiple sources. My highest recommendation.

Common questions

Can you help with the methods section of an IES or NSF proposal?

Yes. Grant methods sections and sample-size justifications are typical deliverables, and Dr. Yel serves as a peer reviewer on the Institute of Education Sciences' Statistics and Modeling panel. Talk to us before you submit so the design and the analysis plan can be settled first.

Can you plan one analysis across a multi-site randomized trial?

Yes. Our team supported a multi-site randomized trial across 22 colleges with one coordinated analysis. The proposal for your study would specify the sites, the clustering and the analysis plan.

Do you do psychometric or IRT work for assessments?

Yes. Psychometrics and IRT are listed deliverables, alongside survey review and measurement recommendations.

Does the $15M+ figure on this page mean your fees?

No. It describes the total funding of research projects our team has supported. It is not a fee.

How much does it cost, and how long does it take?

We don't publish a price list because cost depends on scope. The free 30-minute consult ends with a scoped proposal that includes methods, a timeline and a fixed quote, whether or not you hire us. If you have a deadline, such as a resubmission date, tell us on the first call so the timeline is built around it. We reply to inquiries within one business day.
