Narrative:
Flying the VOR approach to runway 10 at cll. My student correctly flew the arc at 2;000 feet but after reaching illed and turning inbound; descended to 1;300 feet MSL to cross the VOR at that altitude. Reaching 1;300 feet; we were advised to climb to 2;100 feet; then 2;000 feet to cross okige at 2;000 feet. We complied; and the rest of the approach was flown without incident. The student and instructor were too focused on the profile view of the approach plate and did not notice in the plan view to cross okige at 2;000 feet. Okige was not even listed in the profile view at all. This led to the breakdown in situational awareness and the early descent.
