Wanted to make you aware Tableau goes around to major cities offering classroom training. They swing through Houston periodically. Here are upcoming Houston classes for October and December offering Fundamentals and Advanced training sessions. They are $1,400 each, which is a consideration. But you won’t have the travel time and expense to go elsewhere for the same content.
I’ve attended both these classes a few years ago and found them very helpful in jump starting newbie Tableau users. They cover a lot of content hands on with the Tableau instructor there to coach you through the exercises. Back then I was told to bring my laptop with Tableau loaded. They don’t make that clear in the information I reviewed. So if you do signup, double check whether you need to bring it or if they will have their own equipment set up.
