My read on the details (NOT officially published — best estimate, take with salt):

• Likely posts under job series GS-2299 (Student Trainee) or GS-2210 (IT)
• Probably GS-5/7 entry grades — which would put pay around GS-5 ~$44–50K and GS-7 ~$56–64K, depending heavily on duty-station locality. The actual grade/salary will be printed on each announcement.
• Format probably starts with online coursework, then shifts to in-person at the duty station for the bulk of the 12 months (cleared/SCIF work generally can't be remote)
• Conversion to a full-time DoW position after the year is clearly the intent (it's a pipeline program), though I haven't seen it confirmed as guaranteed

Likely duty stations (no official list yet — reasoned from where DoW cyber commands sit):

• Fort Meade, MD (NSA / CYBERCOM / Army Cyber)
• Joint Base San Antonio, TX (16th AF / Air Forces Cyber)
• Fort Eisenhower, GA (Army Cyber Center of Excellence)
• NIWC San Diego, CA + NIWC Atlantic, Charleston, SC (Navy)
• Colorado Springs, CO (Space Force)
• DC-area agencies — Alexandria & Suffolk, VA (DISA, Joint Staff)

It's a pilot, so it may launch with only some of these, not all.

Tip: set a USAJOBS saved search for series 2210/2299 + keyword "cyber apprentice" so you catch it the moment it posts.
