Mgawanyo wa shule ndani ya Dola umejengwa juu ya msingi wa wastani wa umri wa wanafunzi badala ya mihula ya masomo, ili kuzingatia kanuni za Shari'ah zinazohusiana na ufundishaji na nidhamu, ili kushughulika na wanafunzi kulingana na umri wao. Shule zimegawanywa kulingana na makundi haya ya umri katika aina 3 kama inavyoonyeshwa kwenye jedwali lifuatalo:

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:

Shule haifungwi kwa mihula ya masomo peke yake; badala yake inaunganishwa na shule za hatua iliyotangulia na inayofuata kwa idadi ya mihula, ili kuhakikisha wanafunzi wanasambazwa katika hatua tatu kulingana na makundi ya umri wao. Shule ya hatua ya kwanza ya kufundisha ni kwa wanafunzi walio chini ya miaka kumi pekee, huku mwanafunzi akiwa amekamilisha mihula 12 ya masomo anapofikisha umri wa miaka kumi (miaka 4 mara kozi 3 kwa mwaka = kozi 12). Hata hivyo, mwanafunzi makini anaweza katika hatua hii kukamilisha mihula 16 ya masomo (miaka 4 mara mihula 4 kwa mwaka = mihula 16). Kwa hiyo, shule za hatua mbili za kwanza zinaingiliana katika kufundisha mihula inayohitajika ya 13-16 kwa wanafunzi wenye umri wa kati ya miaka 9 na 12; kwa mfano, muhula namba "15" unafundishwa katika hatua ya kwanza kwa mwanafunzi makini asiyetafuta mapumziko katika muhula wowote, na umri wake utakuwa (6+4/15 = miaka 9 ¾), yaani ndani ya kundi la umri la hatua ya kwanza. Kwa mwanafunzi anayetafuta likizo, umri wake utakuwa (6+3/15 = miaka 11), yaani ndani ya kundi la umri la hatua ya pili. Mwingiliano huu upo pia kati ya shule ya hatua ya pili na shule ya hatua ya tatu, ambazo zinaingiliana katika kufundisha mihula "25-32", ambayo ni ya lazima kwa wanafunzi wenye umri wa kati ya miaka 13 na 17. Kozi ya 28, kwa mfano, inafundishwa katika hatua ya pili kwa mwanafunzi makini asiyechukua mapumziko katika kozi yoyote; umri wake utakuwa (6+4/28 = miaka 13), yaani ndani ya hatua ya pili. Vivyo hivyo, kozi ya 28 inafundishwa katika shule ya hatua ya tatu kwa wanafunzi wanaochukua mapumziko kati ya kozi: umri wake utakuwa (6+3/28 = miaka 15 1/3), yaani ndani ya makundi ya umri wa hatua ya tatu. Hali hii ndiyo inayotumika kwa mihula yote inayoingiliana kati ya hatua hizo zilizotajwa katika jedwali la ukurasa wa 74.

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.
