This information is from the 2006 version of the Shuttle Crew Training Catalog USA002960 Rev G., which is unfortunately not online. I've put it on my list to upload. You will note a lot of flexibility allowing the training flow to be customized for each individual depending on their role (first and last paragraphs of the text part).
Payload Specialist Training
The Astronaut Office is responsible for
outlining the Payload Specialist (PS) training curriculum. Specific
training requirements for each PS are determined by the Crew Support
Office manager and the crew payload commander. These training
requirements are incorporated into the detailed crew training plan
developed by the MOD training manager. Training for PSs is composed of
generic and flight-specific training. PS training is intended to
achieve the following:
• Provide sufficient shuttle systems training
so that PS activities onboard the shuttle are conducted in a safe
• Provide sufficient crew interaction and operations training
so that the entire crew can operate safely as a disciplined,
• Provide sufficient emergency and safety training so
that hazardous situations can be handled with speed and skill.
Provide sufficient time for payload training so that experiment
operations proficiency can be maintained.
which are recommended for PSs are listed throughout the Crew Training
Catalog (CTC). Each Crew Training Requirements Table contains crew
position columns which define which lessons each crewmember will
receive. Payload Specialist lessons will be indicated using the “PS”
column. No facility lessons will be scheduled for the backup PS.
However, backup PSs are encouraged to attend facility lessons with the
prime PS, as an observer, if space is available. Re-designation of the
prime PS within 4 months of launch could affect the satisfactory
completion of the training requirements.
A list of self study
materials and a flow chart depicting the recommended PS training may
also be found in the CTC appendix. This flow chart integrates lessons
from each CTC section.
Training outlined in the Shuttle CTC will be
augmented for a specific mission based on the requirements of the
Payload Integration Plan (PIP) Training Annex, and those of the
mission Commander, Payload Commander, Simulation Supervisor, and
Training Team Lead.
Here is the material from the appendices. Note that the flowchart starts at the bottom of the first page and works up, then follow the connector labels.
I haven't done my usual thorough job of explaining the acronyms because this chart is basically all acronyms. Hopefully many are obvious, if you need info on some specific ones please ask in a comment.
