Omega Schools was set up in 2009 by Ken Donkoh (a local entrepreneur from Ghana) and James Tooley as a for-profit business with a social mission to create private schools that benefit low income families and empower the aspirations of those at the bottom of the income pyramid.  By July 2012 the number of Omega schools had increased to ten, enrolling 6,000 children and following the recent investment from Pearson the company now plans to expand the chain across Ghana. An important innovation pioneered by Omega Schools has been the introduction of the daily fee which caters for the many parents that cannot afford to pay monthly or termly fees.  This fee covers tuition costs, uniform, books, transport, de-worming programmes and a hot meal. Each child also receives fifteen free school days a year and an insurance policy which guarantees that every child will complete their schooling in the event of the death of a parent. The popularity of the pay-per-use business model applied to schooling is highlighted by the fact that the demand for places at each new Omega School has been high and the same model is now being introduced by a number of competing private schools in the local area. As noted on their website, Omega Schools is now looking to introduce rapid incremental innovations
