Until not so long ago (15 to 20 years), in Ecuador as well as in Argentina, some high schools prepared students to be primary school teachers and they were called Escuelas Normales . Students graduated as primary teachers and needed no other academic title. What confuses me is if the text is talking about the students that come from those schools or the trainers of those students... It would be useful if you gave us a little more information.

Hi! al menos en Argentina, las escuelas normales otorgaban el título de 'maestras/os normales' a quienes terminaran la secundaria (este era el sistema antes de que el magisterio se convirtiera en una carrera terciaria). Actualmente las escuelas normales imparten educación común, como en cualquier otra escuela. Sólo les quedó el nombre de 'Normales'

Where and when is this from? The word 'Normal Schools' was used in English in the past with the same meaning. If it's historical I can send you useful material. Otherwise you could try 'trainers' for 'docentes'. They are after all 'teacher training colleges' nowadays.
