Kazi ya taasisi hizi ni kuandaa kikosi cha kiufundi na ufundi stadi katika fani ambazo hazihitaji kina cha kisayansi, kwa mfano useremala, ufundi wa chuma, ushonaji, upishi n.k. Mwanafunzi ambaye hataki, kwa sababu yoyote ile, kuendelea na elimu ya shule, anaweza kuacha shule baada ya kukamilisha kozi yake ya 24 na kujiunga na taasisi hizi ili kusomea mojawapo ya fani hizo.

These institutes’ function is to prepare a technical vocational force in specializations that do not require scientific depth e.g. carpentry, ironwork, tailoring, cooking etc. The student who does not wish, for any reason, to pursue school education may leave it after completing his 24th course and join these institutes to study one such specialisation.

Wataalamu huamua muda wa masomo kwa kila chaguo hizi, pamoja na asili ya somo analosoma mwanafunzi na stadi zinazohitajika ili kukamilisha ufundi huu. Mwanafunzi anapofaulu katika taasisi hizi, hupewa cheti kinachojulikana kama "Cheti cha Ufundi" katika useremala, ufundi chuma, ushonaji, n.k.

Experts determine the study period for each of these options, as well as the subject nature that the student studies and required skills to perfect these vocations. Upon success in these institutes, the student is awarded a certificate known as a “Vocational Certificate” in carpentry, ironwork, tailoring, etc.
