Thank you for your comment.
If you’re husband is still interested in becoming a project manager I would Project Management Professional (PMP). This is the ideal and most sought after certification as authorised by Project Management Institute. Almost all PM related jobs, activities and other professions would enquire this qualification. PMI configured this comprehensive certification program for project practitioners of all education and skill levels. There are currently five credentials available, rigorously developed, worldwide accredited and easily transferable between borders and industries.
Regardless of where your husband is in his career, PMI’s PMP is the reliable and conducive certification for your husband. This qualification will enable him to demonstrate his expertise and commitment to the profession he intends to get into. You can find more from PMI’s website resources why PMI’s certifications are the top choice for project practitioners. I work for Firebrand Training providing professional PMI PMP classroom based courses. I’m bit sceptic about how my help to you might be viewed by forum regulators as I have a lot of respect for these kinds of discussions. But to be objective, I think your husband has sparked an interest in a special area which’s highly profitable, exciting and tough at times. These are some of the other certification your husband might consider:-
• Certified Associate in Project Management (CAPM)®
• Program Management Professional (PgMP)®
• PMI Scheduling Professional (PMI-SP)®
• PMI Risk Management Professional (PMI-RMP)®
Speaking of books that’ll help with you preparation, this book has recommended as one of the best by industry experts,
• PMP Exam Prep: Rapid Learning to Pass PMI's PMP Exam-On Your First Try! ISBN: 9781932735185
I also suggest that once you’ve read this book or any other book in your list you first have a go at online practise test which's downloadable at no cost or available at your request. This is one of the best ways to assess what you’ve already learnt without jumping into conclusions or actual training.
I hope I’ve been of some help. Take care.
