Here's the format of my resume:

My name, my email and my cellphone # (top, centered)
Professional Summary (6-10 sentences) below my name

Relevant Work History (underlined)

Here's where I usually tailor my resume for each job for admin support roles that I apply for.

Job Title, Company Name, City/State, dates worked
Summary in 1-3 sentences of job duties
Bullet list of job duties

Education Work History (underlined)

Where I list my teaching work history

Job Title, School Name, City/State, dates worked
Summary in 1-3 sentences of job duties
Bullet list of job duties

Education (underlined)

1st Masters degree, date of graduation
2nd Masters degree, date of graduation
1st Bachelors degree, date of graduation

If you can suggest a different format? I have used functional with no luck. I've used chronological with very little luck.
