The approach ↓
The approach

Tutoring that builds the child, not just the grade.

01
Coaching
Every lesson carries coaching elements that empower students, encourage imperfect action and build confidence - so children learn to try, stumble and try again without fear.
02
Mentoring
Being guided and directed in the right direction - an experience Cathleen gives to tutees and their families alike, so progress continues well beyond the lesson.
03
NLP practice
Neuro-Linguistic Programming - the study of language, experience and excellence - used to help children reframe how they see their own ability.
