The Infrastructure Transparency Index (ITI) Manual measures levels of transparency and the quality of processes related to public infrastructure at  national and sub-national levels. Collaboratively designed and based on international good practice and lessons learned, its objective is to provide stakeholders with quality information that serves to promote transparency and improve the management of public infrastructure.

This manual sets out a methodology for calculating a score for evaluated procuring entities in a national or sub-national context. The individual scores are then used to generate an Index that compares the evaluated procuring entities. It is based on the enabling conditions for strengthening transparency in the sector plus the transparency-related practices applied on recently completed infrastructure projects.

In its design, the manual interprets transparency in a broad and practical sense, not only by looking at it through the traditional lens of access to information, but also by considering associated enablers and capacities. These include citizen participation that leads to the creation of public value through access to information.
