Final answer:
The Evangelical Foreign Missions Association is recognized as the organization that provided a structured platform for missiological studies.
Step-by-step explanation:
The organization that provided a forum and venue for missiological study is the Evangelical Foreign Missions Association (EFMA). As evangelical denominations experienced growth, missiological study became increasingly important to support the global mission and evangelistic efforts. While the Assemblies of God Theological Seminary, the Missions Department of Central Bible College, and the National Association of Evangelicals all play roles within the broader framework of evangelical Christianity, it was the EFMA that specifically focused on foreign missions, and by extension, provided a structured platform for the study of missiology.
