Because the certification is optional (the law just requires that each student TAKE a CPR class, not become certified), only if students are told that certification is optional, may a district charge for the card.
If the student cannot satisfactorily provide proof of having completed a CPR course, have the student take another CPR course. What constitutes satisfactory proof is left to local schools to determine.
That student should be excused by school administrators. The requirement is mandated only for "physically able" students, and determining who is physically able is left to the judgment of local school officials.
The psychomotor component provides skills training and practice that can prepare a student to perform high quality chest compressions. The inclusion of this requirement means that an online-only CPR course will not meet the requirement of the Healthy Kids Act.
Prior to graduating, a student in a school district or accredited nonpublic district must complete a course in CPR. There is no requirement that the student receive a certification for having completed the course.
