Hydrologic Technician, GS-1316

Definitions:

EXPERIENCE: One year of work experience is twelve months working full-time (at least 35-40 hours per week). Part-time experience can be pro-rated (i.e., a year at 20 hours per week is credited as 6 months of experience). If your position consisted of mixed duties, experience credit is given for the percentage of time that you spent on qualifying duties (i.e., if you held a position for 2 years, full-time, consisting of 25% personnel work and 75% budget work, and then applied for a budget position you could calculate your experience as follows: 2 yrs = 24 months. 24 months x 75% [percentage of time spent on budget duties] = 18 months of qualifying experience.)

EDUCATION: One year of full-time academic study is 30 semester hours, 45 quarter hours, or the equivalent in a college or university, or at least 20 hours of classroom instruction per week for approximately 36 weeks in a business or technical school. This education must have been successfully completed and obtained in an accredited business, technical school, college or university for which high school graduation or the equivalent was a prerequisite.

GRADUATE EDUCATION: In the absence of specific graduate program information, a year of graduate education is 18 semester hours or 27 quarter hours of graduate level college course work, or the number of credit hours the school attended has determined to represent 1 year of full time study. This education must have been obtained in an accredited college or university.
