Complex projects such as PIRLS cannot be accomplished by only one agency or organization. Throughout the course of PIRLS, the National Center for Education Statistics works with multiple partners.
||The International Association for the Evaluation of Educational Achievement (IEA) serves as the international coordinating body for the PIRLS studies.|
|The PIRLS International Study Center at Boston College directs the studies at the international level including the design, operations, analysis, and reporting.|
|RTI managed the United States implementation of PIRLS 2016.|
