This study uses the Mathematics Teaching Efficacy Belief Instrument (MTEBI), adapted and translated into Ethiopian Amharic, to ascertain preschool teachers' efficacy views towards early math teaching in Hawassa City. Participants in the research were teachers who work in both public and private preschools in Hawassa City. Forty-four preschool teachers participated in the data collection.

There was no significant difference among KG teachers' efficacy beliefs on teaching beforehand early math in their time of experience. Also, there was a significant difference between private and public preschool teachers’ efficacy beliefs in teaching early math. Keywords: belief; efficacy; kindergarten teacher; math; teaching
