1997, the IIT-JEE was conducted twice after the question paper was leaked in some locations. Between 2000 and 2005, an additional screening test was used alongside the main examination, intended to reduce pressure on the main examination by allowing only about 20,000 top candidates to appear for the examination, out of more than 450,000 applicants. In 2002, an additional exam called the AIEEE was introduced, and it was used for admissions to many institutions of national importance other than the IITs. In June 2005, The Hindu newspaper led a campaign for reforming the IIT-JEE to eradicate the "coaching mania" and to improve gender and socio-economic diversity. Two possible solutions were proposed - either a convergence between the screening test and the All India Engineering Entrance Examination (AIEEE), or a two-tier examination. Whereas ranks from the first tier can be used to gain admission to the NITs and other engineering colleges in the country. In September 2005, the group of directors of all the IITs announced significant revisions to the examination. These were implemented from 2006 onward. The revised examination consisted of a single objective test, replacing and abolishing the earlier two-test system with screener. In the revised examination, to be eligible for taking it, candidates in the general category had to obtain at least 60% aggregate marks in the 12th-grade examinations organized by various educational boards of India, while candidates belonging to Scheduled Castes (SC), Scheduled Tribes (ST), and Persons With Disabilities (PwD) categories needed a minimum score of 55%. In 2008, the director and the dean of IIT Madras proposed further revisions to the examination, arguing that the coaching institutes were "enabling many among the less-than-best students to crack the test and keeping girls from qualifying". They expressed concern that the present system did not allow for applicants' 12 years of schooling to have a bearing on admissions into IIT. In 2008, the Indian Institutes of Technology began offering their admission tests in Dubai. Annually, the number of candidates for the examination in Dubai varies between 200 and 220. In 2013, the AIEEE was renamed JEE (Main), and IIT-JEE was renamed JEE (Advanced); the JEE (Main) had become the screening exam for JEE (Advanced). The two-tier reform suggested in 2005 may become a reality as the Indian government has announced plans for a single entrance exam for all engineering colleges from 2018, with students aspiring for the IITs having
