“…Several researchers have tested the reliability of the HTKS, and the data show strong psychometric properties with little variability across studies, including coefficient alpha, test–retest reliability, and interrater reliability (Cameron et al, 2012 ; McClelland et al, 2014 ; Lipsey et al, 2017 ; Zhang and Rao, 2017 ; Hee et al, 2018 ; Liu et al, 2018 ; Spiegel and Lonigan, 2018 ; Cerino et al, 2019 ; Sezgin et al, 2019 ). Some studies have also found the HTKS predictive of academic outcomes and significantly related to children's working memory, attentional flexibility, and inhibitory control (Cameron Ponitz et al, 2008 , 2009 ; Gestsdottir et al, 2014 ; McClelland et al, 2014 , 2021 ; Schmitt et al, 2014 , 2017 ; Fuhs et al, 2015 ; Lipsey et al, 2017 ; Hee et al, 2018 ; Gonzales et al, 2021 ).…”
