The Project Preparation and Implementation Support Trust Fund, or PPISTF, is a single-donor trust fund that provides technical assistance (TA) grants for project preparation to nonsovereign and sovereign operations. The fund helps build a pipeline of well-prepared and technically sound investment projects and achieve full and timely project results for intended beneficiaries. It supports project readiness activities aimed at improving project preparation, including design and procurement readiness, and reduces start-up and implementation delays so that expected results are fully achieved on time. 

In 2024, $1.1 million was allocated to three TA projects—one for a water sector TA in Uzbekistan and one each for an agriculture sector in Sri Lanka and Thailand (as part of a regional TA).
