Houston ISD Board Policy EIC Local states that to be ranked in the top 15% of their class, students must be enrolled in the school from which he or she is graduating from the first day of the junior academic year, with the exception of students classified as migrant or homeless, in foster care, or with a parent who was relocated due to military service after the first day of the junior academic year. Students who do not fall in these categories but with exceptional circumstances may appeal to the district registrar for consideration no later than 10 calendar days after the rankings have been issued. The decision of the Registrar’s Office is final.
