A core facility — also called a research core or, in federal cost-accounting language, a service center or recharge center — is a centralized, shared research resource that provides instruments, technologies, technical services, and expert consultation to multiple investigators, labs, or departments rather than to a single principal investigator (PI). Per NIH’s own operational definition, a core facility is typically “a discrete unit within an institution” with dedicated personnel, equipment, and space, whose costs are recovered — in whole or in part — through user fees charged to the grants and projects that use it.
Core facilities sit at a genuine intersection of research administration and financial operations: unlike an ordinary sponsored project, a core facility must be capitalized and staffed up front, then run as a self-sustaining (or subsidized) operation whose billing rates are themselves subject to federal cost-accounting rules. This guide covers what makes something a core facility, how these facilities are typically funded and established, how fee-for-service cost recovery works under the Uniform Guidance, and the administrative/governance structures that keep a core facility both scientifically useful and audit-compliant.
What Is a Core Facility?
The operational test is shared, centrally managed access: a resource qualifies as a core facility when it is administered by the institution (not by one PI’s lab), serves users across multiple PIs, labs, or departments, and recovers some or all of its operating cost through a billing mechanism rather than being fully absorbed into one project’s direct costs. The NIH describes core facilities as “centralized shared research resources that provide access to instruments, technologies, services, as well as expert consultation and other services to scientific and clinical investigators” (NOT-OD-13-053).
That definition draws a useful line against two things a core facility is not:
- Not a single lab’s shared instrument. A confocal microscope that one PI’s lab owns and occasionally lets a colleague use, informally and without a billing rate, is not a core facility — there’s no institutional administration, no published rate, and no obligation to serve users outside that lab.
- Not a department’s general-purpose equipment room. A core facility is defined by the service it provides (sequencing, imaging, a specific assay platform) and by having its own cost-accounting identity, not simply by being centrally located.
Common Types of Core Facilities
Core facilities are most common in the biomedical and physical sciences, where instrumentation is too expensive or too specialized for any single lab to own and maintain. Typical examples include:
- Genomics/sequencing cores — next-generation sequencing, microarray, and library-prep services
- Imaging cores — confocal, electron, and light-sheet microscopy; small-animal imaging
- Flow cytometry cores
- Proteomics/mass spectrometry cores
- Biostatistics/bioinformatics cores — analytical and consultation services rather than physical instrumentation
- Animal facilities/vivaria — husbandry and procedural support for animal research (governed separately by IACUC oversight, in addition to the financial rules below)
- Structural biology, NMR, and crystallography cores
The professional body most closely associated with this space is ABRF (the Association of Biomolecular Resource Facilities), founded in 1989, which organizes core administrators and staff into technology-specific research groups (flow cytometry, genomics, proteomics, microscopy, and others), runs an annual meeting, and publishes shared-resource best-practice guidance across several thousand members and hundreds of member facilities.
How Core Facilities Are Established and Funded
Core facilities are typically capitalized through a combination of institutional investment (start-up/capital funds, indirect-cost recovery reinvestment), philanthropic gifts, state funds, and federal instrumentation grants — rarely through a single project grant, since the whole point of a core is that its cost is shared across many users and projects rather than charged to one award.
The primary federal mechanism for acquiring shared, high-cost instrumentation is the NIH Shared Instrumentation Grant (SIG) Program, an S10 activity-code mechanism administered by NIH’s Office of Research Infrastructure Programs (ORIP). As of the current funding opportunity (PAR-24-265), SIG awards range from $50,000 to $750,000 for equipment such as microscopes, imaging systems, mass spectrometers, sequencers, and flow cytometers. A parallel High-End Instrumentation (HEI) Grant Program (also an S10 mechanism, PAR-24-264) covers higher-cost instruments, roughly $750,001 to $2,000,000. Both programs:
- require the institution, not an individual investigator, to apply on behalf of a documented group of NIH-funded investigator-users;
- do not allow indirect (F&A) costs to be charged against the award; and
- run on an annual cycle, historically with a spring notice-of-intent and a June application deadline — confirm the current cycle’s exact dates directly on the NIH funding opportunity page before planning around them.
Equipment purchased through SIG/HEI generally becomes shared core-facility infrastructure rather than the property of a single lab, which is why these programs are the funding-side counterpart to the cost-recovery rules covered next.
Cost Recovery: Fee-for-Service, Recharge, and Rate-Setting Under 2 CFR 200
Once a core facility exists, it has to recover its operating costs — staff time, consumables, maintenance, and often a share of the instrument’s depreciation — from the researchers who use it. This is the “recharge center” or “service center” side of core facility administration, and for any institution that receives federal funding, it is directly governed by the Uniform Guidance (2 CFR Part 200) cost principles, specifically 2 CFR 200.468, “Specialized service facilities”.
The core requirements under 200.468 are:
- Actual-usage billing. Where costs are material, they must be charged directly to the awards and users that actually consumed the service, based on a published schedule of rates or an established methodology — not allocated as a blanket indirect charge.
- Non-discrimination. The rate methodology may not discriminate between activities charged to federal awards and any other activity of the institution, including the institution’s own internal (non-grant-funded) usage. A core facility cannot quietly charge federal grants more than it charges internal users for the identical service.
- Break-even design — no profit. Rates must be “designed to recover only the aggregate costs of the services.” A core facility is not permitted to operate as a profit center; it recovers cost, not margin.
- Periodic rate review with carryforward. Billing rates must be reviewed and adjusted at least biennially, and that review must account for any over- or under-recovery from prior periods — a facility that collected more than its actual costs in one period must credit that surplus against future rates, and a facility that under-recovered may build the deficit into the next rate cycle.
NIH’s own core-facility-specific guidance, NOT-OD-13-053 (“FAQs for Costing of NIH-Funded Core Facilities”), applies these Uniform Guidance principles specifically to NIH-funded cores and confirms the general recovery model: a core facility “recover[s] their cost, or a portion of their cost, of providing service in the form of user fees that are charged to an investigator’s funds, often to NIH or other federal grants.” NIH is explicit that this notice does not create new policy and does not cover every institutional recharge center — it interprets existing cost principles for the core-facility case specifically.
Internal vs. External Rates, and Subsidization
Most institutions publish a tiered rate schedule: an internal rate for the institution’s own faculty (often the federally compliant, full cost-recovery rate used on grant-funded work), and a higher external rate for outside users, since 200.468’s non-discrimination rule constrains pricing between federal and non-federal activity but does not require identical pricing for genuinely external customers. Many core facilities are also partially subsidized — the department, school, or central research office covers part of the operating cost so the user-facing rate stays lower than true full cost — which is common and allowable, provided the subsidy is applied consistently and the billed rate still reflects actual, documented costs rather than an arbitrary number.
Relationship to the Institution’s F&A (Indirect Cost) Rate
Because a core facility’s costs are recovered directly through a billing rate, those same costs are ordinarily excluded from the institution’s facilities-and-administrative (F&A) cost pool used to negotiate its overall indirect cost rate — a cost that is billed directly to a project should not also be embedded in the overhead rate charged to that same project. This consistency requirement is one of the reasons core-facility cost accounting is treated as its own compliance discipline rather than folded into general departmental budgeting: getting it wrong risks a double-recovery finding in a federal audit.
Governance and Administration
Because core facilities combine scientific operations with federally regulated billing, institutions typically govern them through a layered structure:
- A core facility director or manager — usually a PhD-level scientist or senior technical staff member responsible for day-to-day operations, service quality, and staff supervision.
- An oversight or advisory committee — faculty users and institutional financial administrators who review rate proposals, usage policy, and (where a core is federally funded and subsidized) equity of access across departments.
- Central research administration or the sponsored programs office — responsible for ensuring rate methodologies actually comply with 2 CFR 200.468 before they’re published, and for defending those rates if questioned in a federal audit or a Single Audit finding. See how central vs. departmental research administration typically divides this kind of responsibility.
- Institutional finance/cost-accounting office — maintains the rate calculation, tracks over/under-recovery for the required periodic review, and coordinates with the institution’s F&A rate proposal to avoid double-counting core costs.
Professionally, core administrators are increasingly recognized as a distinct research-administration specialty: ABRF’s Core Administrators Network (CAN) is dedicated specifically to the operational, financial, and management side of running a core facility, separate from the technology-specific research groups focused on the underlying science.
Frequently Asked Questions
What’s the difference between a core facility and a recharge center or service center?
“Core facility” describes the research-operations concept — a shared, centrally administered scientific resource. “Recharge center” and “service center” describe the same thing from the cost-accounting side — the billing mechanism a core facility uses to recover its costs under 2 CFR 200.468. In practice, most core facilities are also recharge/service centers, and the terms are frequently used interchangeably in institutional policy documents.
Can a core facility charge federal grants and internal users different rates?
No — 2 CFR 200.468’s non-discrimination requirement means the rate methodology cannot charge federal awards more than the institution’s own internal, non-grant-funded usage for the identical service. Institutions can, however, charge a different (typically higher) rate to genuinely external users outside the institution.
Can a core facility make a profit?
No. Under 2 CFR 200.468, billing rates must be “designed to recover only the aggregate costs of the services” — a core facility is a cost-recovery operation, not a revenue center. Rates must be reviewed at least biennially, with any prior over- or under-recovery credited or built into the next rate cycle.
Does core facility revenue count toward my institution’s indirect cost rate?
Generally, no. Costs recovered directly through a core facility’s billing rate are excluded from the institution’s F&A cost pool, since a cost charged directly to a project should not also be recovered again through the indirect cost rate applied to that same project.
Who funds the equipment a core facility uses?
Most core facilities are capitalized through a mix of institutional capital funds, philanthropic gifts, and federal instrumentation grants — most notably NIH’s S10 Shared Instrumentation Grant (SIG) and High-End Instrumentation (HEI) programs, which fund equipment acquisition but not ongoing operating costs, and which do not allow indirect costs to be charged against the award.
Is there a professional certification or standard body for core facility management?
There is no single accrediting standard analogous to, say, CoreTrustSeal for repositories. The closest professional home is ABRF (Association of Biomolecular Resource Facilities), which publishes best-practice guidance, runs a Core Administrators Network, and organizes technology-specific working groups, but institutional core facility governance and rate-setting compliance remain locally defined, within the boundaries set by 2 CFR 200.468 and, for NIH-funded cores, NOT-OD-13-053.
