John Ouma Otieno, ICT, Computer Science and Mathematics Teacher

Teaching the language of the future, one learner at a time

From a Year 1 learner's first line of Scratch to a Year 11 candidate reaching for a grade 9, I teach children across four countries to think clearly, build boldly and prove what they know.

Every lesson is planned to Pearson and Cambridge standards. Every result is measured. Nothing is left to chance. I walk my candidates through all three Pearson milestones: Year 6, Year 9 and Year 11.
