Bringing in an evaluation consultant can be a flexible and cost-effective way to access specialized expertise, whether your organization needs support with data analysis, survey design, reporting, facilitation, or a defined evaluation project. At the same time, successful consultant engagements require more than simply finding the right person. They depend on clear goals, thoughtful coordination, and strong internal systems.
The Consultant Support Guidance Document helps nonprofit and social impact organizations determine whether the consultant model is the right fit for their needs and prepare for a successful engagement. It outlines the benefits of working with independent consultants, including flexibility, specialized expertise, custom scopes of work, and greater control over priorities and timelines, while also highlighting the internal coordination and quality management responsibilities this model requires.
Before engaging a consultant, organizations are encouraged to assess whether they have the infrastructure needed to manage the relationship well. This includes having a clear internal point of contact, systems for tracking deliverables and communication, capacity to coordinate multiple workstreams, and clarity about how consultants will complement existing staff and one another.
The guide walks organizations through the full consultant engagement process, including:
- Clarifying evaluation needs and identifying where specific skills or additional capacity are needed.
- Establishing a realistic and equitable budget.
- Identifying and vetting consultants for expertise, values alignment, communication style, and cultural fit.
- Developing a clear scope of work with defined deliverables, milestones, timelines, and payment structures.
- Onboarding consultants into the organization’s systems, context, communication practices, and decision-making structures.
- Managing progress, quality, payments, and coordination throughout the engagement.
- Closing out the work thoughtfully and capturing lessons learned.
- Maintaining relationships with strong consultants for future needs and referrals.
Throughout the resource, BSRI emphasizes that consultant relationships work best when both parties have a shared understanding of what success looks like. Clear scopes, regular communication, thoughtful onboarding, and consistent feedback help prevent misalignment and create stronger partnerships. The guide also encourages organizations to think beyond the immediate project by documenting lessons learned and strengthening internal systems for future engagements.
This resource is particularly useful for:
- Nonprofits preparing to hire an evaluation consultant.
- Organizations seeking specialized expertise for a defined project or deliverable.
- Teams considering using multiple consultants with complementary skills.
- Leaders who want to better understand the internal capacity required to manage external support.
- Organizations looking to strengthen their consultant contracting, onboarding, and project management practices.
When managed well, the consultant model can give organizations access to the right expertise at the right time while maintaining flexibility as needs evolve. The strongest engagements are built on clarity, coordination, shared expectations, and a commitment to producing work that is both high-quality and useful.
