This cluster-randomized trial included 64 schools (child N 1,876). The program incorporated workshops and in-classroom coaching. We found moderate to large positive impacts on observed emotional and instructional support as well as classroom organization in prekindergarten classrooms after 1 year of the program. After 2 years of the program, moderate positive impacts were observed on emotional support and classroom organization. No significant program impacts on child outcomes were detected at posttest (1 marginal effect, an increase in a composite of self-regulation and low problem behaviors, was observed). Professional development for preschool teachers in Chile can improve classroom quality. More intensive curricular approaches are needed for these improvements to translate into effects on children.}, number = {5}, journal = {Developmental Psychology}, author = {Yoshikawa, Hirokazu and Snow, Catherine and Barata, Clara and Gomez, Celia and Leyva, Diana and TreviƱo, Ernesto and Weiland, Christina and Moreno, Lorenzo}, year = {2015}, note = {shortDOI: 10/f632xg KerkoCite.ItemAlsoKnownAs: 10.1037/a0038785 10/f632xg 2405685:J52Y2D26}, pages = {309--322}, }
