The growth of low-cost private schools in Pakistan, which have now become a major force in the country’s education system, has received well-deserved attention in scholarly and development practitioner circles around the world. But much less attention has focused on the broader ancillary services ecosystem in the private sector that sustains public and private schools in the country. Behind the scenes, hundreds of critical goods and service providershave formed their own marketplacesin the realms ofteacher training, school security, education technology tools, stationary, suppliesand textbooks. Despite hardships imposed by the pandemic in recent months, the rapid uptake of technology offered a rare bright spot, but not without challenges associated with access inequities.Parents in public and private schools continue investing in their children’s future through a burgeoning marketplace for both traditional providers offering textbooks and uniforms, to servicers offering tuitions and technology solutions. Schools too are spending significant sums in services like teaching training and student security and are being served by a series of new providers who are quickly creating lasting demand for these services. But this growth is not without challenges, not the least of which is a lack of regulatory frameworks governing ancillary services in general and dire shortage of resources (or debt financing options) for schools and parents to invest in these key services. Pakistan’s education research-policy landscape suffers from a dire shortage of systematically collected data on ancillary services, in the absence of which this paper is an attempt to undertake a landscape mapping of key markets.
