Our most durable and familiar product is our suite of available on-site classes. Each one builds upon previous classes so that a combination can take a group of developers through a large change in only a few days. Complete novices in Perl can start with our Perl I class safe in the knowledge that we will not assume they have any prior experience. Developers who have already been programming in Perl can start later in the series to suit their tastes. Our classes are structured to follow an initial progression designed to get programmers to the point where they can use object-oriented modules, at which point the world is their oyster, figuratively speaking, because they can use the massive CPAN library to leverage the output of hundreds of experts. At that point our offerings branch into covering domain-specific topics so that prospective students can choose what's most applicable to their interests and work.
