The continuing educational programme of Likhaan for over fifty years — teaching creativity, inventive thinking, and technological innovation across the Philippines, from classrooms to the national training system.
The InventSchool™ was organised on 7 July 1973 as the training unit of Imbensyon Pilipino — originally named Likhaan Institute — and has been the continuing educational programme of Likhaan ever since. Institute and school have been considered one and the same organisation from the beginning.
From 1981 to 1985 the programme was implemented jointly with the Philippine Inventors Commission (later the Philippine Invention Development Institute), which carried it until 1987. The Technology Application and Promotion Institute (TAPI) of the Department of Science and Technology then reactivated the training under the name Invent School Program in 1988 — the national programme that continues today, for which Likhaan conducted the trainers' courses across Luzon, the Visayas, and Mindanao in 2011.
The programme's accumulated teaching materials were compiled into the Basic Course in Creativity, Inventive Thinking and Technological Innovation (CITTI) — Training Guide for Trainers, published as an eBook in 2013–14 and in a revised print edition by Likhaan Agglomerates in 2024.

Selected, documented moments from the InventSchool record.

Under the reorganised Likhaan Institute of Creatology and Innovation, The InventSchool™ Philippines serves as the Institute's invention education and training centre — and the first programme to open as the Institute's education offering comes back into full operation.
Its remit continues what fifty years built: creativity, social productivity, and technology innovation training for professionals, engineers, entrepreneurs, teachers, students, youth, and children — alongside the InventClub™ tradition in schools, and the festival-and-congress culture that connected the Filipino inventing community for decades.
