The president directs the actions of the Junta of Castile and León and plays a coordinating role among Council members.

The seat of the presidency is at the School of the Assumption of Valladolid, whose original blueprints from 1902 are attributed to Santiago Guadilla.

The President is chosen by the Cortes of Castile and León, can be removed by them if he or she loses the support of more than half of the representatives, and has the capacity to appoint and dismiss the ministers.

At the head of each ministry there is a minister, who is appointed freely by the President, and each one is subdivided into departments that coordinate and direct the administrative services.

In addition each ministry has a general secretary, various departments and even diverse autonomous branches and state-owned companies.
