ARS § 15-901: "Homebound" or "hospitalized" means a pupil who is capable of profiting from academic instruction but is unable to attend school due to illness, disease, accident, or other health conditions who has been examined by a competent medical doctor and who is certified by that doctor as being unable to attend regular classes for a period of not less than three school months or a pupil who is capable of profiting from academic instruction but is unable to attend school regularly due to chronic or acute health problems who has been examined by a competent medical doctor and who is certified by that doctor as being unable to attend regular classes for intermittent periods of time totaling three school months during a school year. The medical certification shall state the general medical condition such as illness, disease, or chronic health condition; that is why the pupil cannot attend school. Homebound or hospitalized includes a student who is unable to attend school for a period of less than three months due to a pregnancy if a competent medical doctor, after an examination, certifies that the student is unable to attend regular classes due to risk to the pregnancy or to the student's health.
