JEE Main Exam History

The Joint Entrance Examination (JEE) Main is one of India's most competitive engineering entrance examinations. It was initially introduced in 2002 as the All India Engineering Entrance Examination (AIEEE) to create a standardized admission process for engineering aspirants across the country.

In 2013, AIEEE was replaced by JEE Main to streamline admissions into engineering institutes and create a two-stage selection process:

• JEE Main – Screening examination for engineering admissions.

• JEE Advanced – Entrance examination for admission into IITs.

Major Changes in JEE Main Over the Years

Shift to Online Mode

Initially conducted in pen-and-paper format, JEE Main transitioned to a Computer-Based Test (CBT), making the examination process more efficient and transparent.

Conducted by NTA

The responsibility for conducting JEE Main was transferred from CBSE to the National Testing Agency (NTA), ensuring greater standardization and fairness.

Multiple Exam Sessions

To reduce pressure and provide flexibility, students are now allowed multiple attempts within the same academic year, with the best score being considered.

Today, JEE Main serves as a gateway to some of India's most prestigious engineering institutions.

About the National Testing Agency (NTA)

The National Testing Agency (NTA) is an autonomous organization established by the Government of India to conduct entrance examinations fairly and transparently.

The NTA conducts several national-level examinations, including:

• JEE Main

• NEET

• CUET

• UGC NET

The agency uses advanced technology and standardized processes to ensure accurate assessment and reliable results.

JEE Main Important Dates

The National Testing Agency generally conducts JEE Main in multiple sessions every year.
