español al inglés Ciencias sociales Educación / Pedagogía Job titles

SPAIN. This is a school staff job description from an article about school principals and leadership. There is no other context, the title appears after a comment the person made about the principal's management style. The other commenters are different types of teaching staff like former principals, substitute teachers, regular teachers…. I know what it means (a clerical and administrative worker) but am looking for a more succinct title. Target audience is US English.
