Fingerprinting Infrastructure Modernization for Child WelfareThe Fingerprinting Infrastructure Modernization for Child Welfare program supports state and tribal child welfare agencies in upgrading their fingerprinting and background check systems to speed up the approval of caregivers and expeditesafe placements for children. Funding is directed toward deploying mobile fingerprinting units and office-based Live Scan stations to integrate fingerprint collection directly into existing child welfare processes like home visits and licensing workflows. This modernization aims to eliminate systemic delays that have historically slowed caregiver approvals, reducing administrative burdens while ensuring compliance with federal standards. The initiative is designed to deliver measurable improvements in background check processing times, increase the number of qualified caregivers available for placement, and enhance the overall capacity of agencies to place children in stable, nurturing homes more quickly. These efforts align with the Administration for Children and Families’ A Home for Every Child initiative, strengthening the broader child welfare system by expanding access to kinship, foster, and adoptive families and promoting placement stability through more efficient, integrated infrastructure. The program is administered by the Department of Health and Human Services through the Administration for Children and Families, with inquiries directed to Brian Lerner at cb@grantreview.org.

JOFOC for Personnel Security Support Services Bridge ContractThis contract is a sole-source bridge justification for personnel security support services awarded to iWorks Corp. under FAR 6.103-1(c)(2)(ii) to ensure uninterrupted continuity of critical national security vetting and adjudication operations for the Defense Counterintelligence and Security Agency. The base period runs from July 5, 2026, through November 4, 2026, with a six-month option period exercisable under FAR 52.217-8 to extend performance through January 4, 2027, preventing any disruption following the expiration of the prior contract on July 4, 2026. Work is performed primarily in Hanover, Maryland, supporting DCSA’s Trusted Workforce 2.0 initiatives and compliance with Security Executive Agent Directive 6, requiring all contractor personnel to hold active Top Secret/SCI clearances due to the nature of the classified environments and sensitive data involved. The incumbent's unique institutional knowledge, proprietary methodologies, and direct access to classified systems make it the only responsible source capable of delivering these services without unacceptable risk to national security; transitioning to a new vendor would result in prohibitive delays due to clearance processing times and the complexity of operational continuity. The contractor, classified as an Other than Small Business, is required to comply with FAR 52.244-5, necessitating a subcontracting plan to maximize opportunities for small businesses despite the sole-source nature of the award. No pricing details, CLINs, or contract value are provided, and while payment and invoicing mechanisms are unspecified, the contract is structured as firm-fixed-price with performance grounded in stringent quality benchmarks inherited from the prior contract. The contract explicitly prohibits service interruptions, acknowledging that even a single day of downtime would be unacceptable, and anticipates duplicate funding during any transition overlap to maintain mission readiness.
