Past winners and funding trends for this program
Build and Broaden (B2) supports fundamental research and research capacity across disciplines at minority-serving institutions (MSIs) and encourages research collaborations with scholars at MSIs. Growing the science, technology, engineering and mathematics (STEM) workforce is a national priority. National forecasts of the impending shortage of workers with science and engineering skills and essential research workers underscore a need to expand opportunities to participate in STEM research (President's Council of Advisors on Science and Technology, 2012). MSIs make considerable contributions to educating and training science leaders for U.S. economic growth and competitiveness. Yet NSF has received comparatively few grant submissions from, or involving, scholars at MSIs. Targeted outreach activities reveal that MSIs have varying degrees of familiarity with funding opportunities within NSF and particularly within the Social, Behavioral and Economic (SBE) Sciences Directorate. As a result, NSF is limited in its ability to support research and training opportunities in the SBE sciences at these institutions. With its emphasis on broadening participation , Build and Broaden is designed to address this problem. SBE offers Build and Broaden in order to increase proposal submissions, advance research collaborations and networks involving MSI scholars, and support research activities in the SBE sciences at MSIs. Proposals that outline research projects in the SBE sciences that increase students' pursuit of graduate training, enhance PI productivity build research capacity, or cultivate partnerships are especially encouraged to apply. Proposals are invited from single principal investigators based at MSIs and from multiple co-investigators from groups of MSIs. Principal investigators who are not affiliated with MSIs may submit proposals, but must collaborate with PIs, co-PIs, or senior personnel from MSIs and describe how their project will foster research partnerships or capacity-building with at least one MSI as a primary goal of the proposed work. Proposals may address any scientific and cross-disciplinary areas supported by SBE. These areas include anthropology, archaeology, cognitive neuroscience, decision science, ecological research, economics, geography, linguistics, law and science, organizational behavior, political science, public policy, security and preparedness, psychology, and sociology. To find research areas supported by SBE please visit the SBE programs page or visit the NSF funding and awards page. Funding Opportunity Number: 22-638. Assistance Listing: 47.075.

The goal of the Archaeology Program is to fund research which furthers anthropologically relevant archaeological knowledge. In accordance with the National Science Foundation’s mission such research has the potential to provide fundamental scientific insight. While within the broad range of “archaeology” the focus is on projects judged to be significant from an anthropological perspective, the Program sets no priorities based on time period, geographic region or specific research topic. The Program administers four competitions each of which is described below. It also supports projects submitted under NSF-wide competition guidelines. These include CAREER, EAGER, RAPID and Research Experiences for Undergraduates Supplement requests. Doctoral Dissertation Research Improvement Awards (DDRI) For a detailed description of the Archaeology Program DDRI competition, see Solicitation NSF 15-554 which can be accessed via the Archaeology DDRI web site. It contains additional rules not presented in this synopsis. The DDRI competition provides up to $20,000 (+ university indirect/overhead costs) to permit graduate students enrolled in US universities to conduct dissertation research. The student need not be a US citizen or national. While the student writes the proposal and conducts/supervises the research, the dissertation advisor serves as the Principal Investigator and the student is listed as the Co-PI. Salary and normal living expenses are not eligible costs but per diem and most other research expenses are allowable. Both field and non-field projects are funded. Proposals may be submitted at any time and applicants are normally informally notified of the likely outcome within three months. Applications are sent for evaluation to six individuals (“ad hoc reviewers”) specifically selected for subject matter expertise. Students are allowed to resubmit one time if their original proposal is declined. Unless Program Officer dispensation is obtained, a student, through their advisor, may submit only two proposals (an original submission and a resubmission if necessary). Senior Archaeological Research The Archaeology Program holds a twice yearly competition to provide support for senior investigator archaeological research. The target dates, as noted above, are July 1 and December 20. (In contrast to “deadlines”, “target dates” permit leeway as determined by the Program Director.) Each proposal is sent to a set of ad hoc reviewers and is also evaluated together with the other applications submitted in that round by a broadly based panel of anthropological archaeologists. Grants are normally two to three years in duration. In the US Government fiscal year 2018 (FY18), the average award (including both direct and indirect costs) was approximately $172,000 with individual grants ranging from $29,000 to $312,000 in size. Archaeometry Research Awards The Archaeology Program administers an annual “archaeometry” competition with a target date of December 1. The goal is to fund projects either to develop/refine anthropologically relevant archaeometric techniques and/or support laboratories which provide relevant services. Examples of the former include the development of methods to identify specific types of organic residues on ceramics or development of field applicable analytic techniques. Service laboratories which, for example provide dating trace element, isotopic and dendrochronological analyses illustrate the latter. Projects which apply standard archaeometic techniques with the goal to answer specific archaeological questions should be submitted to the “senior” archaeology competition. Data archives, in common with archaeometric laboratories, function to strengthen basic archaeological infrastructure. Therefore, Principal Investigators may submit proposals through the archaeometry competition to assist in meeting this goal. Proposals are evaluated by both ad hoc reviewers and a panel composed of individuals who combine both archaeological and archaeometric expertise. Awards (including indirect costs) are normally two to three years in duration and in FY18 ranged from $99,000 to $188,000 in size. The average award was $144,000. High Risk Research in Biological Anthropology and/or Archaeology (HRRBAA)(See Solicitation NSF 19-570which can be accessed via the HRRBAA program web site.) This competition is designed to permit the submission of high-risk, exploratory proposals that can lead to significant new anthropological knowledge. Because of a highly competitive environment, proposals that have both a high risk of failure and the potential for significant payoffs are less able to compete with standard research proposals. This program is designed to provide a mechanism whereby risky proposals with a great potential for advancement of the discipline can compete for funding. The risk involved in such endeavors must significantly exceed that associated with regular archaeology research projects. “Risk” in this context refers to risk of project failure and not risk of site destruction. The competition is also not intended to provide “start-up” grants. Maximum awards are limited to $35,000 in total cost and proposals may be submitted at any time. They are evaluated by ad hoc reviewers only. In FY18 the HRRBAA program did not make anyhigh risk awards. NSF Required Data Management Plan All proposals must include as a supplementary document a plan for data management and sharing the products of research. The data-management plan to be submitted with a proposal must be no longer than two (2) pages in length. This supplementary document should describe how the proposal will conform to NSF policy on the dissemination and sharing of research results. For more information about this requirement, please see the NSF Proposal & Award Policies & Procedures Guide (PAPPG), Chapter II.C.2.j. Please note: the SBE Directorate has additional guidance for proposals submitted to SBE programs, please see Data Management for NSF SBE Directorate Proposals and Awards. Questions should be addressed to John Yellen via e-mail (jyellen@nsf.gov). While the Archaeology Program does not sponsor, endorse or have an official arrangement with any data archive it would note that two organizations provide this service: Open Context (https://opencontext.org) and The Digital Archaeological Record - tDAR (https://www.tdar.org). One may contact Open Context’s Editor (publish@opentext.org) for further information and info@digitalantiquity.org which maintains and develops tDAR. In addition to the NSF guidance, you may find the guidance provided by the Society for American Archaeology (SAA) helpful. Additional resources can be found at the SAA site. When necessary, applicants may request funds to implement a data management plan.
