The glocal volunteer movement of evaluators and first-time explorers

Build the movement. Strengthen evidence. Create lasting impact.

About

What Eval Corps is

Somewhere right now, extraordinary work is going unmeasured, unheard, and unlearned from. Eval Corps is the glocal volunteer movement of evaluators, MERL professionals, technologists, and first-time explorers who show up for the organizations the world isn't measuring, and for each other.

Glocal: global in reach, local in roots.

Eval Corps is HubForge's free MERL support programme, rebuilt and renamed from HubForge Impact Lab. Volunteers give their skills pro bono to nonprofits, grassroots groups, and social enterprises that cannot afford evaluation support. Visit the platform →

The gap

The problem it exists to solve

That is one gap seen from three sides, not three separate problems:

01

Organizations

Nonprofits, grassroots groups, and social enterprises around the world lack access to quality Monitoring, Evaluation, Research & Learning expertise. Their work is harder to prove, learn from, and grow.

02

Professionals

Thousands of experienced evaluators, researchers, data professionals, and technologists want meaningful ways to contribute their knowledge beyond their day jobs. There is no simple way to do it.

03

Young people

Many who want to explore MERL have nowhere to start: no mentor, no real project, no structured way to find out whether evaluation is the work they want to build a career on.

Eval Corps exists to close that gap by bringing all three worlds together.

Why we're here

Vision

We believe the world doesn't just need better evidence. It needs a movement of people who refuse to let good work go unmeasured, unheard, and unlearned from, and a real door in for the next generation who want to learn how.

This is bigger than any single evaluation. We're building the people, the practice, and the movement that outlasts us all.

What we stand for

Values

Collaboration

The most meaningful change is created together.

Ownership

We take initiative, lead with purpose, and honour our commitments.

Learning

We remain curious, reflective, and committed to continuous improvement.

Inclusion

We embrace diverse perspectives and create opportunities for everyone to contribute.

Integrity

We uphold ethical, transparent, and credible evaluation practice.

Service

We use our knowledge and skills to strengthen others and create lasting impact.

Our commitment

The three promises

1

Management: you will always know what you signed up for

Every role has a written scope before you start: what you'll do, how long it takes, and what "done" looks like. Every volunteer has a named point of contact, not a general inbox. Onboarding takes no more than one session. Two to three hours a week means two to three hours a week.

2

Experience: you belong here, wherever you're starting from

A first-year MERL student and a twenty-year evaluator both have a real seat, by design. Recognition is built into the workflow, with mentorship in both directions.

3

Impact: you will see what your time built

Every engagement closes with a visible outcome, recorded in plain language in the Impact Log, with no jargon. That running log is the cumulative footprint of Eval Corps. If you volunteered, your piece of it is on that page.

The line we hold. We would rather grow slower and keep this promise than grow fast and break it. If Eval Corps ever has to choose between recruiting more volunteers and taking care of the ones we have, we choose the second.

For organizations

Your work deserves evidence.

Nonprofits, grassroots groups, and social enterprises anywhere in the world can request focused MERL support from experienced volunteer professionals. Pro bono, under signed standards, end to end. Costs nothing.

5–15 HRS PER ENGAGEMENT

Evaluation design

A practical evaluation or learning framework for a programme: questions worth asking, indicators that fit your context, and a plan your team can actually use.

5–15 HRS PER ENGAGEMENT

Data review

Expert eyes on data you already have: what it can honestly support, what it can't, and how to tell the story it actually tells.

5–15 HRS PER ENGAGEMENT

Framework input

Feedback on a theory of change, MEL plan, or funder report draft, grounded in recognized evaluation standards.

Every engagement is delivered under a written scope and signed confidentiality standards. One matched volunteer. Project-based. No cost.

Find your place

15 roles. Four pathways in.

You don't apply to a role directly. You choose a pathway based on where you're starting from. The specific role is a conversation once you're in, never a silent placement.

PATHWAY 01

New to MERL entirely

Student or early-career, exploring whether evaluation is your field. Routes to the Explorer tier: a 3-month programme, 2-3 hours per week, with a paired mentor and a supervised micro-MERL project with a real output.

PATHWAY 02

Adjacent skills

You write, facilitate, translate, or organize, and you're MERL-curious. Routes to Contributor roles like Storyteller, Translator, Convener, or Event Support.

PATHWAY 03

Practicing MERL professional

You do evaluation, research, or data work today and want to put your craft to work pro bono. Routes to Contributor roles: Mentor, Consultant, Reviewer, Toolkit Contributor, or Technologist.

PATHWAY 04

Senior, 10+ years

You've led evaluations, teams, or organizations and want founding-team responsibility for a workstream. Routes to the Leadership tier: Strategy, MERL Standards, Community, Partnerships, or Knowledge.

Nobody is declined for inexperience alone. Inexperience routes to the Explorer track, which comes with a mentor and a supervised first project.

The process

What happens after applying

A real person replies within seven days, and that is a metric Eval Corps tracks, not a pleasantry. Accepted volunteers get a written role scope, a named contact, one onboarding session, a mid-engagement check-in, and a closing conversation with an Impact Log entry. A contribution letter is available on request.

When you join you sign one short agreement: you'll honour the commitments in your written scope, follow the Code of Conduct and Evaluation Ethics, and keep partner organizations' information confidential. Volunteering creates no employment relationship and no financial obligation in either direction.

Ecosystem

An ecosystem initiative. By definition, not alone.

Eval Corps exists to strengthen evaluation ecosystems, and ecosystems are built with partners. It works with VOPEs, universities, funders, multilaterals, conveners, and organizations rooted in their regions.

VOPEs

Volunteer Organisations of Professional Evaluators, connecting national and regional evaluation communities to the Eval Corps movement.

Universities

Academic partners that provide Explorer-track students, research linkages, and a bridge between evaluation theory and practice.

Funders & multilaterals

Foundations, bilateral agencies, and multilateral organizations that believe the evaluation field is strengthened when the next generation is invested in.

Eval Corps is a signatory to the Youth in Evaluation manifesto, the Eval4Action campaign's commitment to long-term, meaningful engagement of young and emerging evaluators. Its work is aligned to the Global Evaluation Agenda 2.0. These are commitments Eval Corps has made, not endorsements given to it.

Join the movement

Whether you're an experienced evaluator, a first-time explorer, or an organization that needs MERL support, Eval Corps is free in both directions. Contact: evalcorps@gmail.com
