About the founder
Full-time teacher & founder of Grade 9 School
Jacobo Priegue is a full-time language teacher with 12 years’ experience across independent, maintained and international education settings. His work combines day-to-day classroom practice with assessment, publishing and educational technology.
He is the founder of Grade 9 School, author of Cambridge IGCSE Spanish as a First Language Coursebook, and has seven years’ experience in examining, including marking, vetting and setting official papers.
Grade 9 School began with a straightforward classroom question: how can students practise languages more often and receive useful feedback without creating an unmanageable workload for teachers? The platform is Jacobo’s answer to that question.

Grade 9 School began with Jacobo’s own students and the everyday challenge facing language teachers: how to provide more frequent, meaningful practice and feedback without creating an impossible marking backlog.
The platform is designed around real classroom workflows, combining language practice, assignments, feedback and engagement in one place for teachers and their students.
