Home Access Center or HAC, is an online tool for McKinney ISD students and parents to find the most recent information regarding student attendance, grades, assignments and class schedules.

• The school year consists of two semesters, each consisting of approximately 90 days.

• A student will earn credit for a course only if the final grade is 70 or above. For a two-semester (1 credit) course, the student’s grades from both semesters will be averaged and credit will be awarded if the combined average is 70 or above. Should the student’s combined average be less than 70, the student will be required to retake the semester in which he or she failed.

• According to state law, students must attend 90 percent of the days a class is offered to receive credit.

• Grades in all subject areas will be defined by two categories:

  • Summative - These grades will comprise 70% of a student’s grade average in the course. (Students will complete a minimum 3 summative grades per quarter)

  • Formative - These grades will comprise 30% of a student’s grade average in the course. (Students will complete a minimum 10 formatives grades per quarter)
