A better starting point

Start with the decision, not the method.

You do not need a finished research plan before speaking with us. Bring the program decision that feels uncertain; we will help shape the right evidence pathway.

01

Your decision

What must your team learn?

Clarify the program choice, funding question, or learning priority the evaluation needs to answer.

02

Your reality

Where is the program now?

Map your timeline, implementation stage, existing data, partners, constraints, and ethical requirements.

03

Your pathway

What evidence will be useful?

Choose a proportionate design: RCT, quasi-experimental approach, diagnostic analysis, or stronger monitoring.

How we help

Rigor from design through delivery.

View all services
01

Design

Build an evaluation that can answer the question.

Research questions, theory of change, power and sample size, randomization, pre-analysis planning, and quasi-experimental alternatives.

  • RCT and quasi-experimental design
  • Power analysis and sampling
  • Evaluation protocols
02

Field systems

Protect data quality before problems become expensive.

SurveyCTO and ODK instruments, enumerator workflows, real-time checks, back-checking, monitoring, and field-team support.

  • Survey programming
  • Quality-control systems
  • Field operations support
03

Analysis and learning

Move from estimates to decisions people understand.

Transparent econometric analysis, reproducible workflows, clear visual communication, policy translation, and hands-on team capacity building.

  • Stata, R, and Python analysis
  • Decision-ready reporting
  • Training and mentoring

Research that survives contact with the field

Methodological depth. Operational judgment.

Strong evaluations depend on thousands of small implementation decisions. Our experience spans research design, multi-wave survey operations, data-quality systems, analysis, publication, and communication with donors and public-sector partners.
