* Latin Proficiency: A strong command of Latin was absolutely essential. Almost all instruction was in Latin, and applicants needed to demonstrate a sufficient level to participate in classes. This was tested informally during an interview process.
* Religious Commitment: Harvard was founded as a Puritan institution to train ministers. Therefore, a demonstrable commitment to Puritan beliefs and a strong moral character were paramount. This was assessed through recommendations and interviews that would gauge the applicant's piety and adherence to the prevailing theological views.
* Recommendations and Character References: Applicants were expected to obtain recommendations from respected community members, often clergymen, who could vouch for their character and academic abilities.
* Age: Applicants were generally expected to be at least fourteen years old, though there was some flexibility.
* Financial Resources: While not explicitly stated as a requirement, prospective students (or their families) needed to be able to afford tuition and living expenses. Harvard was not free.
In essence, admission in 1639 was a matter of demonstrating suitability, based on religious conviction, Latin competence, and a good character reference, rather than fulfilling a checklist of academic achievements. The process was heavily reliant on personal assessment and community standing.
