“…In SWPBS schools, secondary-level interventions are usually research-based standardised interventions or group-based programmes for practising certain specific skills (Horner, Sugai, and Anderson 2010). Check in check out (CICO) is one of the most studied secondary interventions in SWPBS schools to support pupil's prosocial behaviour (Drevon, Hixson, and Wyse 2018;Hawken et al 2014;Maggin et al 2015;Mitchell, Adamson, and Kenna 2017). Core principles of CICO support include clearly defined behavioural expectations, precorrections for meeting these expectations, regular positive feedback for the demonstration of appropriate behaviour, use of data-based decision making and a daily system for home-school communication (Crone, Hawken, and Horner 2010).…”
