Admission to the Indian Institutes of Technology (IITs) without taking the Joint Entrance Examination (JEE) is not possible. The JEE is the primary and mandatory entrance exam for undergraduate engineering programs at all IITs across India.

The JEE is a highly competitive examination that evaluates a student's proficiency in physics, chemistry, and mathematics. It consists of two stages: JEE Main and JEE Advanced. To be eligible for JEE Advanced, which is specifically for admission to the IITs, candidates must first clear the JEE Main.

Here are some key points to consider:

1. Mandatory Requirement: JEE is the standard and universally recognized route for entry into IITs. Admission to IITs is solely based on merit, and the competition is intense due to a limited number of seats and a large number of aspirants.

2. Alternative Routes: While JEE is the primary pathway, other engineering colleges and universities may offer their own entrance exams or consider scores from other national-level exams for admission. However, these options do not apply to IITs.

3. Changing Policies: Admission policies and procedures can change over time. It's essential to check the latest updates from the Indian Institutes of Technology and relevant authorities for any potential changes in admission criteria or alternative routes to IITs beyond my last knowledge update in September 2021.

4. Preparation: Aspiring candidates should dedicate substantial time and effort to prepare for JEE exams, as they are highly competitive and require thorough subject knowledge and problem-solving skills.

In summary, as of my last update, JEE remains the primary and essential means of securing admission to the Indian Institutes of Technology. Any changes or alternatives to this admission process would be subject to updates by the relevant authorities and institutions. It's advisable to stay informed about the latest developments in IIT admission procedures.
