The Human Resource Development (HRD) ministry Wednesday launched the All-India Survey on Higher Education (AISHE) 2014-15, an annual, web-based, pan-India exercise on the status of higher education in the country.The annual survey collects data on several parameters, including student enrollment, examination results, education finance and infrastructure.The data helps in making informed policy decisions and conducting research in education development."So far, the ministry has released the final reports of the AISHE 2011-12 and provisional reports of the AISHE 2012-13, which are in the public domain. While the survey exercise is in its fourth consecutive year now, the AISHE 2013-14, launched on June 17, 2014, is also underway," said an official statement."With the launch of the AISHE 2014-15 in October, the time lag in dissemination of higher education statistics has been eliminated," added the statement.
