Does the airforce active duty accept adult high school diplomas?

I dont believe its the same as a ged because there was a ged program, It’s from the county school board but called an adult high school diploma from the actual adult high
School because He had to complete 8 credits that He was missing to graduate high school that He completed at an adult high school, this is for my brother, he is 19 years old. Will the airforce active duty accept this? Or would this be tier 2?
