Can a German researcher be Lead PI?

Only if affiliated with a US institution at submission. International researchers usually join as Senior Personnel or Co-PI at a US institution - the US institution holds the grant. Pure international PIs apply through equivalent programmes at home (DFG, ERC).

How long from submission to award?

Typically 6-9 months. Most NSF divisions have target deadlines (often once or twice a year); the panel meets ~3 months after deadline, decisions ~2 months after the panel, grant agreement ~2 months after decision.

NSF Standard Research Grant: applying to the US National Science Foundation

Open to US-based PIs and international collaborators on co-funded projects. The 15-page Project Description is unforgiving but every section is well-defined.

Key takeaways

Typical budget: $200-500k over 3 years for a single-PI Standard Grant.

Two scoring criteria, equally weighted: Intellectual Merit and Broader Impacts.

Submission via research.gov; institutional grants office files - not the PI.

How NSF differs from European funders

The Broader Impacts criterion is unusual: half the score is whether your project benefits society - teaching, mentoring underrepresented students, public engagement, technology transfer. Treat it as a substantive section, not a checklist. Programme Officers (the NSF staff who run each division) are accessible by email and a 30-minute call before submission is normal etiquette.

The 15-page Project Description

Strict 15-page limit (single column, 11pt minimum, 1-inch margins). Standard structure: motivation + research questions, prior NSF support (separate section), research plan with measurable milestones, broader impacts, project management. Over by even one line and the proposal is returned without review. The reference list goes after the 15 pages and has no page limit.

Always submit through your institution's Sponsored Programs Office (SPO) - they need 5 business days minimum.

Co-PIs at non-US institutions are allowed but receive no NSF funds - their part is in-kind.

The panel review

Three reviewers read each proposal in detail, then a panel of 10-20 discusses and rates. Ratings: Excellent, Very Good, Good, Fair, Poor. To be funded you generally need 2 Excellent ratings + 1 Very Good or better. Funding rates vary by division - typically 18-30%. Programme Officers may co-fund proposals that score borderline but address strategic priorities.
