国家内における学校の区分は、学期ではなく生徒の平均年齢を基準に行われる。これは、教育および懲戒に関するシャリーアの規定に従い、生徒を年齢に応じて扱うためである。学校は次の図に示すとおり、これらの年齢区分に従って3種類に分けられる。

The division of schools within the State is built upon the basis of average student age rather than school terms in order to be bound by the Shari’ah rules related to teaching and discipline, so as to deal with students according to their age. Schools are divided according to these age groups into 3 types as shown in the following chart:

学校は学期だけに厳密に縛られるものではなく、むしろ生徒を年齢層に応じて三つの段階に確実に配分するため、一定の学期にわたって前の段階と後の段階の学校と連携している。第一段階の学校は十歳未満の生徒だけを対象としており、十歳に達した時点で生徒は十二学期（年三学期×四年＝十二学期）を修了している。ただし、熱心な生徒はこの段階で十六学期（年四学期×四年＝十六学期）を修了することができる。したがって、第一段階と第二段階の学校は、九歳から十二歳の生徒に必要な第十三学期から第十六学期を重複して教えている。例えば第十五学期は、どの学期も休まない熱心な生徒に第一段階で教えられ、その生徒の年齢は（6+4/15＝9と3/4歳）、すなわち第一段階の年齢層に入る。一方、休暇を求める生徒は第二段階で教えられ、その年齢は（6+3/15＝11歳）、すなわち第二段階の年齢層に入る。この重複は第二段階の学校と第三段階の学校の間にも存在し、両校は十三歳から十七歳の生徒にとって必修となる第二十五学期から第三十二学期を重複して教えている。例えば第二十八学期は、どの学期も休まない熱心な生徒に第二段階で教えられ、その年齢は（6+4/28＝13歳）、すなわち第二段階の年齢層に入る。同様に、学期の間に休みを取る生徒には第三段階の学校で第二十八学期が教えられ、その年齢は（6+3/28＝15と1/3歳）、すなわち第三段階の年齢層に入る。これは、七十四ページの図表に示された、上記の段階間で重複するすべての学期にも当てはまる。

The school is not exclusively bound by school terms only; rather it extends to associate with schools of the previous and following stage in a number of terms in order to guarantee distribution of students in the 3 stages according to their age groups. The first stage school of teaching is exclusively for students less than ten years old, with the student having completed 12 school terms upon attaining ten years (4 yrs times 3 courses per year=12 courses). However, the serious student can at this stage complete 16 school terms (4 years times 4 terms per year=16 terms). Accordingly, schools of the first 2 stages overlap in teaching the required terms 13-16 to students between 9 and 12 years, for instance, term number “15” is taught in the first stage to the serious student who is not seeking a break in any term, his age will be (6+4/15= 9 ¾ years) i.e. within the first stage group. The second stage for the student who seeks the holiday, he will be (6+3/15=11 years) i.e. within the second stage age group. This overlap exists also between the second stage school and the third stage school, they overlap in teaching the term “25-32” which are mandatory for students between 13 and 17 years of age. The 28th course for example, is taught in the second stage for the serious student who does not take a break from any term; his age will be (6+4/28=13 years) i.e. within the second stage. Similarly, the 28th course is taught in the third stage school for the students who take a break between courses: his age will be (6+3/28=15 1/3 years) i.e. within the third stage age groups. This is the case for all the overlapping terms between the mentioned stages in the chart on page 74.
