Here's a breakdown:
* Yes, they select based on criteria: International student selection is inherently selective. Universities and programs have specific criteria they use to choose applicants. These often include:
* Academic merit: GPA, standardized test scores (like TOEFL, IELTS, SAT, ACT), and academic transcripts are key.
* English language proficiency: Demonstrated ability to understand and use English is crucial.
* Financial resources: Proof of sufficient funds to cover tuition, living expenses, and travel is usually required.
* Letters of recommendation: These provide insights into the applicant's character and potential.
* Statement of purpose: This essay allows applicants to showcase their goals, motivations, and fit with the program.
* Extracurricular activities and experiences: These demonstrate well-roundedness and potential contributions.
* Visa eligibility: The applicant must be eligible for the necessary student visa.
* No, it's not arbitrary or discriminatory (ideally): While there's inherent selectivity, reputable institutions strive for fair and transparent selection processes. They aim to avoid discrimination based on race, religion, gender, or other protected characteristics. However, biases can still unintentionally creep in.
* Yes, they might select for specific skills or backgrounds: Some programs might prioritize applicants with specific skills, experiences, or backgrounds that align with the program's needs or research focus. This isn't necessarily discriminatory; it's about finding the best fit.
* It's competitive: Many prestigious programs receive far more applications than they can accept, making the selection process highly competitive. This means even highly qualified applicants might be rejected.
In conclusion, the selection process is definitely selective, using established criteria to assess applicants. While ideally objective and fair, inherent competition and potential unconscious biases mean that it's not a completely random process. The "certain students" selected are those who best meet the specific requirements and priorities of the institution or program.
