Abstract	Individuals differ in their timing of sleep (bed times, rise times) and in their preference for morning or evening hours. Previous work focused on the relationship between academic achievement and these variables in secondary school students. Investigated was the relationship between chronotype and academic achievement in 11,125 ten-year-old children attending fourth grade of primary school. They filled in the "Culture Fair Intelligence Test" (CFT 20-R), the "Skalen zur Erfassung der Lern-und Leistungsmotivation" (SELLMO, scales for the assessment of learning and performance motivation), the short version of the "Five-Factor Personality Inventory Children" (FFPI-C) to measure conscientiousness, and the "Composite Scale of Morningness" (CSM) to assess morningness-eveningness. Mean CSM score was 37.84 ± 6.66, midpoint of sleep was 1: 36 ± 00: 25, and average sleep duration (time in bed) was 10:15 ± 0:48. The multivariate model showed that intelligence was the strongest predictor of good grades. Conscientiousness, motivation, younger age, and an earlier midpoint of sleep, but not CSM, were directly related to intelligence and to good grades. (ZPID).
