Should tech training be required for all current teachers?

In an effort to ensure that all educators are keeping up with technology, some schools have offered tech training for current teachers. But should it be mandatory? Though federal and corporate grants are available for such training programs, such as Microsoft's Partners in Learning [2] program, schools that don't receive grants may need to hire outside specialists, which can get costly. Advocates of tech training believe it is money well spent, but others argue that these lessons are time consuming and ineffective and, without proper follow-up, easily forgettable. Should schools require tech training for every teacher, regardless of proficiency, or should the training be optional? Tell us what you think!
