Hello,
These are some Certifying Bodies that offer In House Training:
DNV-GL
AIB
SAI Global
SGS
NSF
SQFI - Check their website
Alchemy
HEB University
I found that In House Training is very expensive because in addition to the their fee you may have to pay their Traveling Expenses. Also, you have to be committed for the 2-3 day training with no interruptions. (This is very difficult while the operation is running).
Alchemy offers the course on line with testing and I found out this is the inexpensive way to do it. It will be at your own pace. Other CB offer On line certification. I am finding myself taking online courses to keep up with Certifications and industry updates. NSF is one of the best for this type of training as well. Upper management likes this because of no travel expenses.
Check in your area and see what type of training centers (specially your suppliers) are closed to you and may take probably 1-3 hours drive.
Other option is to have one of you to certify as SQF Instructor and offer the class in house on your own and register for the test.
Honestly, classroom training away from the operation is the best setting; but, as costs go up, it is very difficult.
I hope this helps,
Kelio
