CIES 2018 Presentation, given by Sam Ngaruiya. The Ministry of Education (MoE) with technical support from RTI International are collaborating with four county governments to pilot the Tayari ECDE programme. The objective of Tayari is to develop a cost- effective, scalable, low-cost and quality ECDE model. To maximize the impact of Tayari, the MoE intends to scale-up Tayari. However, the ability to take-up and sustain Tayari rests on the counties’ capacity to ensure a viable ECDE system and meet the critical cost of the model. The ability of the counties to take on a Tayari-type programme requires ample institutional, systemic, organizational and fiscal capacity of the counties to take-up and sustain the model. MoE statistics show that, whereas, access has improved, the quality is affected by non-provision of curriculum-aligned instructional materials in the counties and unclear policy in hiring and continuous professional development of the ECDE officers and teachers. Equally, there are policies at the national level that can be used as guidelines for implementation and management of ECD, but there are still some gaps in policy guidelines for implementation; a study mapping the four Tayari counties and three additional counties found increased investment in ECD infrastructure by the governments This presentation explores how the umbrella policy from the MOE as well as evidence from the Tayari pilot programme’s longitudinal study has informed practice within the four Tayari counties, enabling them to be more responsive to the dynamic policy environment. It also showcases initiatives put in place by the counties to sustain the Tayari implementation in pilot counties.
