The leadership of the Baháʼí Faith has created goal-oriented Baháʼí teaching plans, spanning 1-10 years at a time, to spread the Baháʼí Faith. The plans began in the 1930s and 1940s as teaching goals for certain countries and in 1953 became coordinated globally, often with a focus on sending travelling teachers to new countries. Shoghi Effendi initiated the plans before his death in 1957, and the Universal House of Justice has initiated the plans since 1964. Since 2000, the plans have had a focus on Baháʼís becoming trained to facilitate "core activities" of devotional gatherings, classes for children and adolescents, and a systematic study known as "study circles", based on a series of workbooks by the Ruhi Institute.
