A purposive sample of 119 primary school learners from six classes in two government schools in Durban was obtained. The learners assessed their classroom climate with the My Class Inventory (short form) (MCI-SF), and their emotional intelligence with the Trait Emotional Intelligence Questionnaire (Child Short Form) (TEIQue-CSF). The six teachers assessed the school climate with the School Level Environment Questionnaire (SLEQ). Results suggest that classroom climate is a predictor of emotional intelligence while school climate is not; that satisfaction and cohesiveness positively correlate with emotional intelligence levels, and friction, competitiveness, and difficulty negatively correlate with emotional intelligence levels. The identified relationship between classroom climate factors and emotional intelligence warrants further research into the topic. / M.A. (Psychology) / Hierdie studie het ten doel gehad om te bepaal of klaskamerklimaat of skoolklimaat 'n groter voorspeller van emosionele intelligensie by Suid-Afrikaanse laerskool leerlinge van Durban, Kwazulu-Natal is, asook watter faktore die ontwikkeling bevorder en watter die ontwikkeling daarvan belemmer. 'n Doelgerigte steekproef van 119 laerskool leerlinge van ses klasse in twee regering skole in Durban is verkry. Die leerlinge het hulle klasklimaat beoordeel met behulp van die ‘My Class Inventory (short form) (MCI-SF)’, en hulle emosionele intelligensie met die ‘Trait Emotional Intelligence Questionnaire (Child Short Form) (TEIQue-CSF)’. Die ses onderwysers het die skoolklimaat beoordeel met die ‘School Level Environment Questionnaire (SLEQ)’.. Resultate dui daarop dat klasklimaat 'n voorspeller van emosionele intelligensie is terwyl skoolklimaat nie is nie; dat tevredenheid en samehorigheid positief korreleer met emosionele intelligensievlakke, en wrywing, mededingendheid en probleme negatief korreleer met emosionele intelligensievlakke. Die geïdentifiseerde verwantskap tussen klimaatfaktore in die klaskamer en emosionele intelligensie regverdig verdere navorsing oor die onderwerp. / Psychology
