There isn't a secret contract among universities regarding the acceptance of new students, but there are some practices and understandings that might seem like a "gentleman's agreement" among certain elite universities. These can include:
1. Admissions Standards: While each university has its own admissions criteria, there might be some unspoken understanding about the caliber of students admitted. Elite universities often have high standards and look for exceptional academic achievement, extracurricular activities, and personal qualities.
2. Overlap in Applicants: Many students apply to multiple top-tier universities, and these universities are aware of the competition for the most highly sought-after students. Admissions officers may consider where else an applicant has applied or been accepted, though decisions are ultimately made independently.
3. Reciprocal Policies: Some universities may have reciprocal agreements or understandings regarding the transfer of students or collaborative programs. This could extend to things like credit transfers, joint research initiatives, or other academic collaborations.
4. Informal Networks: Admissions officers, faculty, and administrators at top universities often have professional networks and may share information or insights about applicants or trends in higher education.
However, it's important to note that formal collusion or agreements to manipulate admissions would be illegal and unethical. Universities are expected to uphold the integrity of their admissions processes and treat each applicant fairly and independently. Any evidence of collusion or unfair practices would likely be met with severe consequences.
