(Proactive)
Collaborate with the school nurse to ensure that there are not medical or physical reasons why the student might be late (and provide necessary accommodations if this is the case for your student)
If it is 1st period, get to know your students and home environment to better understand why they might be late
Start the class with a preferred activity. Plan the activity with your student and ask that they lead it (if they want)
Provide choice of activities to start the class and allow the students to choose
Provide rewards that allow the student the escape or avoidance they need (e.g., skip homework pass, free time at a time of their choice, a pass to have free time with a preferred adult)
(Consequence)
Have the student make up time missed during free time (e.g., end of class, during lunch, after school)
Hold family/student/teacher conference to develop plan to increase frequency of student arriving to class on time
Use data (e.g., student input, parent input, academic assessments) regarding reasons behind tardiness (e.g., avoiding warm-up activity, subject is difficult for student) and provide alternative activities (e.g., UDL - representation, output, engagement strategies)
Co-construct a behavior contract that outlines a goal and supports (see antecedent strategies for off-task behavior) for the student to use to reach the goal. Provide weekly meetings with the student to review, reteach and reinforce progress
