Terry Evans started his education at the age of 22 by participating in a medium development group in Clapham Spiritualist Church in South London. The larger part of the training received in the beginning of his development can be ascribed to the president of the church, who at that time was Blanche Tilling. During this period he took part in many different lectures and groups teaching the philosophy of mediumship according to the educational guidelines of Spiritual Nationalist Unions (SNU).

In 1982 Terry Evans started his examination as a speaker and demonstrator (i.e. medium) held by the SNU education committee (East London district), and subsequently, in 1985, he was awarded a certificate as a speaker and demonstrator. The education program offered by the SNU is of a very high standard, and in many circles they are seen as having a globally leading position within education.
