Advice: Don’t pay for schooling unless..
If you’re getting into this field, and you’re going through a school that does not offer placement or a way to get your hours.
If not you are back in the same boat as before you started it.
This field can 100% be self study.
Do NOT give “schools” individuals etc your money unless they offer the placement,
If they can’t offer that it’s essentially a pyramid scheme
Personal advice:
Look for Non-Certified roles they exist ( and the best way to get your actual training)
CRCST exam is ZERO about instrument identification and all about processes and rules.
Don’t come into the field thinking it’s a “get rich field” it’s not, most don’t even stay in this field, they move up or move on to becoming a scrub Tech
