The term "selective" when used to prefix a pathology fellowship title also tends to imply ACGME accreditation for that fellowship. In other words, not all general surg path/subspecialty surg path fellowships are ACGME-accredited.
Part of the reason these non-boardable fellowships sought ACGME accreditation was because of J-1 'shippers who needed to be in ACGME-accredited training programs, or would otherwise face being kicked out of the country.
