One of the challenging tasks among pre-school teachers is preparation of self-made teaching media. Using ready-made materials or purchasing media materials quite often does not avail appropriate materials to teachers. This paper aims at pointing out the relationship between pre-school teacher training and preparation time of media materials. Cross-sectional survey design was used for this study targeting pre-school teachers in Nairobi County and Limuru Sub-County, Limuru County. The teachers’ training status included 14 untrained, 22 trainees and 87 trained teachers. Teachers’ systems of training encompassed 91 teachers trained by National Center for Early Childhood Education (NACECE) and 18 teachers from Other Training Agencies (OTA). Teachers were grouped according to their length of training as follows;0.5-1.50 years (13 teachers), and 2.00-3.00 years (96 teachers).Data was analysed quantitatively using the chi-square inferential statistics. The findings revealed that training impacted pre-school teachers in the manner in which they allocated preparation time for media materials. It was concluded that depending on the training status of a teacher, the training system they had undergone and the length of time taken to train the teacher, there were variations in the preparation time of media materials. The researchers recommended that the Ministry of Education should institute a policy requiring that all pre-school school teachers must be trained as a precondition for them to be given placement to any working station. The researchers also recommended that the Ministry of Education should harmonize all the pre-school teacher training systems, soliciting the best practices of media production from each, in a bid to come up with the ideal system of teacher training that would be considered to give appropriate emphasis to preparation of media materials. Further, the researchers recommended that the Ministry of Education should initiate surveillance of pre-school teacher training institutions in order to disqualify overly short courses that do not instil proper practice of media production among teachers.
