What does the 93rd Constitutional Amendment deal with ?

The 93rd Constitutional Amendment Act, 2005, is primarily associated with the insertion of Article 15(5), enabling the State to make special provisions for the advancement of socially and educationally backward classes (OBCs), SCs, and STs regarding admissions to educational institutions [t3]. However, the question refers to the 93rd Amendment Bill (passed as the 86th Amendment Act, 2002), which introduced Article 21A to provide free and compulsory education for children aged 6 to 14 [t8]. In competitive exams, this is often identified as the 93rd Amendment based on its bill numbering [t8]. Other options are distinct: the 92nd Amendment (2003) added Bodo, Dogri, Maithili, and Santhali to the Eighth Schedule [c1][t1][t7]; the 88th Amendment (2003) dealt with service tax [t2]; and the 83rd Amendment (2000) exempted Arunachal Pradesh from SC reservations in Panchayats [c4].
