Laser Safety Course level upgrade! We are pleased to confirm that our UK educational body, OCN Credit4Learning has re-designated the course levels that apply to our two UK/ANZ Core of Knowledge Laser User and LSO courses. They each move up one level to Level 4 and Level 5 respectively. Our previous level 3 Laser/ILS safety course is now level 4, and our previously graded level 4 LSO Safety course is now Level 5. Our credits ratified by OCN for each of our courses are fully recognised and legitimate CPD (or CPE) credits.
