Work Resume vs Graduate School Resume I've been working in corporate IT for the last two years and would like to apply to graduate school for a MA in East Asian Studies.

I was told I should keep my work resume to one page, so I have done that. It wasn't that hard to do because jobs aren't as concerned with your volunteer experience as a masters program would be.

The MA program is asking that I attach my resume. I'd like to add back in my volunteer + other experiences a graduate school would be interested in... but that would put it over one page. 

Is that okay? Is there any difference (apart from content) in the structure/general guidelines of submitting a resume in the work world vs the grad school world?
I am not a fan of the "1 page resume." If you have had a number of relevant educational experiences and work experiences (and relevant volunteer experiences), and it goes over two pages and is in an aesthetically pleasing form (e.g., 10-12-pt font, 1-in margins, etc.), don't worry about it.  I've seen some absolutely horrible resumes where the applicant has tried to cram everything onto a single page, and it is a detriment to that person's application. I haven't had a 1-page resume since just after undergraduate school.

Graduate schools are normally looking for a proper Curriculum Vitae (CV), which would include education, work experience (primarily academic), publications, awards, and possibly references. Now, this isn't to say that you must reformat your resume into a CV, especially if you don't have research/publications/awards/etc., but you do want this document to highlight your experiences to some degree.

Finally, your resume/CV is not as important as some of the other documents you will provide with your package: letters of recommendation, transcripts, and your research/personal statement. Your resume/CV should list the pertinent information from your past, but it will be amplified in your other documents.
