Title VII of the Civil Rights Act of 1964, better known as 'equal employment opportunity', prohibits discrimination by covered employers on the basis of race, color, religion, sex, or national origin. It does not say anything about college degrees or professional certifications so no, legally speaking, requiring such things is not discrimination.

To give the author the benefit of the doubt, I don't think they said it was illegal discrimination. For example, not hiring someone because of their race in 1963 was not illegal, but it was definitely discrimination.

Requiring a credential could be discriminatory if it has a disparate impact on protected classes.

Griggs v. Duke Power Co.[0] is the Supreme Court case on this topic.
