Systematic review of the associations between staff education (AA or Higher; BA or Higher) and child outcomes.
a Abbreviations: AA = Associate’s Degree; BA = Bachelor’s Degree. Symbols bolded are significant and positive, symbols bolded and italicized are significant and negative, and symbols in grey are non-significant. Star = Zero Order Pearson’s Correlation, Unfilled circle = Beta, Filled square = Unstandardized Coefficient, Downward arrow = Effect Size. aTo improve the readability of this complex table, eleven papers [17,21,55–57,61,63,67,70,71,82] that had an outcome that appeared in only that one paper were omitted from this table. Several analyses from other papers that had idiosyncratic outcomes are also excluded. For a comprehensive display of all of the data for all of the child outcomes see Tables A-H in S4 File. bThis paper is one of a series of Meta-Analyses and Systematic Reviews assessing the relationship between child care quality and children’s outcomes; therefore, superscript letters below are in reference to various large databases that samples in these papers were drawn from. These letters have been kept consistent across the series for our readers. cSamples within papers are described in more detail in Table 3 in the manuscript. dAcronyms for child outcomes are listed in S3 File and for journals, large samples and covariates are in S5 File. eIdentifying Letters (also refers to as Alphabet Recognition Test, Naming Letters, and Letter-Naming Test).
