Well, there are two answers here. My understanding is that the ABA doesn't allow 1L's to start sending out resumes until December 1st. At least, that's the case at my school.
There's a huge difference between ABA standards that schools are obligated to follow to keep their accreditation and NALP guidelines. NALP is a completely voluntary organization to join and does not represent all legal employers. The Nov/Dec. 1 guidelines are "General Principles" that NALP encourages schools to adopt, but I don't believe they're binding to any parties (inferring from the language "should") in order to keep their NALP membership. http://www.nalp.org/content/index.php?pid=16#part2 (scroll to bottom) Also, if you send your resume in early, it doesn't seem like there are any serious repercussions. See http://www.nalp.org/content/index.php?pid=24#handle So...if your school didn't adopt that particular NALP standard, and you're interested in non-NALP employers (like a small firm or public interest org), by all means contact them or send your resume in sooner if you think it'll help you.
