Qualifications: All qualifications must be met by the closing date of this announcement-12/29/2025-unless otherwise stated in this vacancy announcement. Credit will be given for all appropriate qualifying experience. To receive credit for experience, your resume MUST clearly indicate the nature of the duties and responsibilities for each position, starting and ending dates of employment (month/year), and the resume must reflect full and/or part-time or total number of hours worked (i.e., work 40+ hours a week, rather than indicating full-time). If part-time, the hours must be annotated to be able to pro-rate the amount of qualified specialized experience. To qualify for this position at the GS-05 grade level, you must possess at least one of the following minimum qualifications by close of the announcement: EXPERIENCE: At least one year of full-time specialized experience comparable to at least the GS-04 grade level in the Federal service. Specialized experience may include: collecting air, water and/or soil samples; preparing samples for processing; monitoring procedures which must conform to timely and established protocols; entering scientific data common to the laboratory environment into a database, or perform similar work in support of laboratory record keeping and document control; writing portions of scientific or technical papers and reports that document research projects; and, operate and maintain equipment such as digital camera, GPS, water quality sensors, particulate sampler, and haze recorder. Resume must include hours/week worked. -OR- EDUCATION: Successful completion of at least a full 4-year course of study leading to a bachelor's degree from an accredited college or university with a major study (or at least 24 semester hours or 36 quarter hours) in any combination in astronomy, physics, chemistry, hydrology, engineering, electronics, geology, oceanography, or other appropriate field of physical science. One year of full-time academic study is defined as 30 semester/45 quarter hours, or the equivalent in an accredited college or university. You must include a copy of your transcripts at the time of application. -OR- Successful completion of a COMBINATION of education and experience as described above. To combine education and experience, first take the number of semester hours (or equivalent) earned towards a bachelor's degree, in excess of 60 semester hours, and divide by 60 semester hours (or equivalent).
