Islamic education is a major part of Granada life. This is manifested in the academic classes taught, the school calendar and extra-curricular activities.

The Islamic Education classes comprise about 30% of weekly instructional time for all students. Islamic education is divided into three components: Quran reading and memorization, Islamic studies and Arabic language. In the lower grades, Quran memorization is emphasized. Students in the upper grades are instructed on the proper reading of the Arabic text of the Quran and its meaning. Islamic Studies curriculum consists of three major parts: beliefs and rituals of Muslims, Islamic History, and morals and manners. The Arabic language is taught in all grades using texts designed for foreign language acquisition. Students in the middle and Junior High grades are divided into levels that match their ability.

In support of Islamic studies curriculum, the school calendar is designed to incorporate major holidays celebrated in the United States as well as major Islamic events. For instance, GIS has a special schedule during the month of fasting (Ramadan). The students are dismissed one hour early, and the last week of the month is off to allow for the extra worship observed at night. The students are dismissed one hour early on Fridays after the Muslim congregational prayer, which is attended by the seventh and eighth grade students in the adjacent mosque. Students in grades three to eight visit the mosque on a daily basis, to offer the mid-afternoon group prayer. Teachers and administrators attend the prayer with the students and instruct them on proper manners of being in the mosque and observing group prayer. All the above activities help the students to learn Islamic teachings and practice them in real life situations.

Schoolwide assemblies, held quarterly, give students the opportunity to perform Islamic songs and skits in front of their peers and helps build a strong Muslim identity. In addition, Eid Celebrations (for the two major Islamic holidays) are designed to celebrate Muslim holidays and reinforce the students’ sense of Muslim identity. The Nasheed Club emphasizes Love and Reverence for Allah through Islamic poetry and songs.
