How to Keep it current
Even if you don't edit your resume regularly, you should try to keep good updated records of what you’ve been doing. You may want to keep your information organized and keep track of important information such as:
a. Your Accomplishments
Listing your accomplishments and demonstrating your ability and skill can set you apart (if they are phrased the right way).
b. Licenses, Degrees, Awards, and Certificates
List only those which are most relevant to your career field. Include titles, dates, locations, and
the sponsors of any training you completed to receive certificates or licensure. An employee only wants to see what's relevant to the position you're applying for.
c. Conferences and Additional Education
Conferences can be important especially if you were able to earn continuing education credits or The Importance of Keeping Your Resume Updated
It is very important to keep your resume up-to-date. When searching for a job, you never know when you might need a resume at the last minute so regularly keep it updated with significant achievements like newly acquired training or trade, recently achieved certifications, and other similar accomplishments instead of trying to remember critical information days, months, or even years after the fact. This is especially true of smaller but equally important achievements that may fade in memory as time passes.
