One way to get training for trial director and summation is to request a sample of the product from the company. Another way is to get on the website for both and see what kind of free tutorials they have online. One other way is to attend HPA's annual CLE this year. We have one of the BEST summation and trial software trainers out there coming to speak. Her name is Charlene Agnew and I have personally taken a few of her training sessions and I always walk away knowing more than when I got there and I have been working with Summation for 7 years now.
A full line up of speakers for the CLE is posted under the 2013 Annual Spring CLE tab or you can go to May 2nd and 3rd, 2013 and pull up all the information.
