With the unique systems of the institutions available in the country which are trying to cater for the direct admission of the students and with the high demand of the seats in the school and different marginalized groups, they have to come up with ways that they can admit such students but in such criteria that they will offer the best seats to the most eligible students without bias and giving them a chance for them to apply and pick them in the right merit. Such institutions with the government directive to ensure that all the group in the country get a chance to join the institutions, they have to consider the direct admission quota seats allocations so that they do not leave out some of the groups that they are supposed to have in the institutions. The institutions can be answerable to a court of law if they do not follow such government directives in the quota seat systems allocation. Some of these quota seat allocations are the management quota seats, institutional, NRI, disability, and many more quota allocation criteria that the institutions have to consider. By going through the article below you can understand some the entry criteria of the students in the institutions and how the quota seats allocation criteria are used so that they can give each marginalized group to have a representative of the same and at the same time having varies students with different capabilities admitted in the institutions.
The management quota seats are the kind of seats that are allocated for the direct merit students in each institution. The other quota seat allocation is the institutional ones that are owned by the institutions at hand and tend to be controlled by the institutions. This two even though tend to be similar they are different in terms of the management quota seats are given by the government to the students who have attained the eligible criteria and therefore have an access to the direct admission positions and which are given to the public institutions and since the private sector is given a chance to cater for the growing demand of the formal education, they also must offer such seats to the management quota before they handle other students. The institutional ones are the most loved seats and therefore given to the students who want to join the specific institution that is offering such seats after they have paid an extra fee and completed an entry exam.
With the disability quotas they are given to people who are impaired, and the NRI Quota Seats ones are given to people who live outside the country or have their fees paid by NRI guardians. To summarize, that is the criteria that students get admission to various institutions. Read more about universities here: https://en.wikipedia.org/wiki/University#Definition.
