Poor school attendance in the early grades is predictive of poor subsequent educational outcomes. We report on a pilot intervention aiming to reduce chronic absenteeism in kindergarten. We designed and implemented a two-way, text-based parent-school communication system to encourage daily attendance, provide parents with personalized feedback on their child's attendance, and provide support to mitigate challenges that threatened parents' ability to get their child to school regularly. The program was well received, with nearly all families registering for participation, and three-quarters of those receiving outreach responding and engaging with school personnel via text. The pilot school's kindergarten chronic absenteeism rate was substantially lower in the intervention year relative to prior trends. Further, in the intervention year, the pilot school's kindergarten chronic absenteeism rate (13%) was substantially lower than for that of a synthetically constructed comparison school (24%). We discuss implications for sustainability and scaling of an effort such as this.
