Human Factors
We have an MVA defined northeast of the field (026 feet) for a group of antennas. Aircraft X was just approaching the depicted antennas at 3000 and was given an approach clearance to maintain 3000 until established. I observed Aircraft X pass the antenna below the MVA at 2400; but past the obstruction. The surrounding MVA being 018; I repeated the clearance. Ref: 7110.65 5-5-9. The skill level of pilots in the ATC system is drastically declining. I have saves every week. Examiners need to stop handing out certificates like bubble gum in a pack of baseball cards.
TLH TRACON Controller reported an aircraft descending below the Minimum Vectoring Altitude (MVA).
