24."When will the next SBIR/STTR solicitation be published?

There are no guarantees on when solicitations will be published, but for the last several years, NSF SBIR/STTR Phase I solicitations have been published twice per year. One solicitation is published in March, with a June deadline, and another is published in September, with a December deadline. The minimum amount of time between the publication of the solicitation and the deadline for proposals will be 90 days."

Assuming the December 2017 deadline.
