First, sorry for coming onto the thread so late, and I apologize in advance if I re-cover any points already made (I haven't read every page).
PADI TRAINING IN A NUTSHELL
1. Success on PADI courses depends upon the diving student meeting a level of "mastery" (correctly, fluidly and repeatable) in specifically designated 'Performance Standards'. These standards are provided for the course as a whole, the academic, confined and open-water sections of training.
2. An instructor, according to their own standards for teaching, may not fail a student for anything other than failing to meet the designated performance standards for that course/module/dive etc.
3. The instructor should fully brief the student on these standards in advance, and what is required to meet them. He should then introduce and demonstrate each specific skill, before allowing the student to practice ("
until the student is comfortable").
4. The student should then be given reasonable opportunity to demonstrate the required skill/s.
5. If performance standards are not met, the instructor should highlight the specific deficit that prevented the student demonstrating "mastery" in the given skill. They should re-demonstrate to correct that deficit.
6. The student should then be given reasonable opportunity to conduct the skill again.
7. Following any session of training, the instructor should fully de-brief the student, paying particular regard to their success (or failure) relative to the pre-stated performance standards.
8. If the student does not meet the performance standards for certification, then the instructor may withhold certification. However, the process should ensure the student is entirely clear on the specific performance standards they failed to meet.
..... was this how the course was conducted? What is the OP's understanding of the specific performance standards they failed to meet, and for what reasons?
PADI Rescue Diver Certification Standards
Course Standards - Certification Requirements
Student divers meet course performance requirements and:
• Complete five knowledge development segments and exam.
• Demonstrate skills from the Self-Rescue Review either in confined or open water.
• Demonstrate skills from Rescue Exercises 1-10 in open water (spread over at least 2 days).
• Participate in Rescue Scenarios 1 and 2.
• Prepare an emergency assistance plan for a dive site.
General Considerations
Conduct all Rescue Exercises in open water. You may introduce and practice them first in confined water.
Just to clarify.... where did failure occur? In a confined water 'introduction and practice' or during the actual teaching/assessment of Rescue Exercises 1-10 in open water?
Theoretically, as I understand it, an instructor cannot "fail" a Rescue Diver student in the 'introduction and practice' during confined water - because they have to conduct the actual exercise in open water.
So, if the student wasn't allowed into open water exercise practice, the only possible reason I could see was if they failed to demonstrate prerequisite diving skills during a pre-dive assessment/check-out.... and the instructor should/could offer a 'Scuba Tune-Up/Review' (
or whatever PADI call it this year...) before starting the Rescue Diver course....
Personally, I wouldn't be so eager to leap to make any recommendations to the OP until I knew, for sure, that they had been instructed properly in the first instance. There's many reasons why a student might not "show confidence or participation" in training - poor instruction is not the least of them..
