Cadre Prime is a cadre of telepaths within Psi Corps who manifested their abilities either at birth or before the onset of puberty. As they account for less that 5% of all human telepaths, they are considered exceptionally rare and special. They are taught that it will be their responsibility to serve as an example to "laters" of what it means to be Corps. However, they do not necessarily represent the strongest teeps in the Corps; Lyta Alexander, for example, was a member of Cadre Prime and a P5, while Alfred Bester, also raised in Cadre Prime, was a strong P12.
