This study investigated the relationship of kindergarten teachers' ratings of their students' 21st century skills (college readiness skills) with students' behavioral and academic performance. Teachers rated the frequency that their students (n = 579) demonstrated persistence, curiosity, affective, and cognitive (e.g., critical thinking) behaviors within their classrooms via the Human Behavior Rating Scale: Brief (HBRS: Brief, a teacher rating scale. The relationship of the HBRS: Brief teachers' ratings was compared with data the school annually collected (behavioral ratings, academic performance, student office discipline referrals [ODRs], and absences). Hierarchical linear modeling indicated that teachers' ratings of students' persistence and cognition behaviors were significantly associated with students' academic performance. Teachers' persistence, curiosity, and externalizing affect ratings were predictive of behavioral ratings and teachers' externalizing affect ratings were significantly associated with ODRs. The results support the efficacy of investigating teacher perceptions of students' 21st century skills with kindergarteners.
K E Y W O R D S21st Century skills, curiosity, HBRS: brief, persistence Kindergarteners are commonly described as exhibiting a thirst for knowledge, a readiness to learn, and as being naturally inquisitive and curious about their environment. Although the term 21st century skills incorporates a diverse variety of domains and skills, there is a consensus that 21st century skills include the critical areas of persistence (e.g., task engagement, sustained attention), curiosity (e.g., exploration, investigation), social-emotional behavior (e.g., affective and interpersonal skills), and critical thinking (e.g., problem solving) behaviors (). For over a decade federal and state educational agencies have recommended that kindergarten standards incorporate a multifaceted approach that addresses 21st century core readiness skills such as curiosity, persistence, critical thinking, and social-emotional behaviors (U.S.
