John Paul Jackson and Streams Ministries International have identified several training centers around the country that provide classes developed by the Institute for Spiritual Development (ISD). These and other classes are offered through Cahaba Equipping Center (CEC) by a number of independent teachers. Michael and Elisa French, both Streams instructors, oversee CEC which is currently located at the Bridge Christian Fellowship in Birmingham, Alabama. Classes are offered at the Training Center in Birmingham and in any other location where a request is made and where a sufficient number of students have interest.
