In the case of Oportunidades, the Mexican government took important initiatives to increase the supply of schools in specific areas of the country by rehabilitating old rural schools and constructing new secondary schools (Levy and Rodriguez, 2004). Further progress towards ensuring an appropriate supply of services could require strengthening collaborations with non-govemmental organisations and community groups (see also Chapters 6 and 7 on education and health challenges, respectively). One particular source of concern in this complex environment is that many public assistance programmes overlap in terms of objectives, benefits accrued and beneficiaries.
