Which tracks someone needs depends on who they are.
IA studenttrains across all three, since their path is not decided yet, and the basics of all three together are what make a person practice ready in whichever field they end up in.
IIA young professionaltrains in the one their own practice already runs on, and takes up a second track when the plan is to switch practice area.
IIIA law schoolruns all three alongside the curriculum, so a batch leaves having trained in each of them, whichever way a student’s path turns out.
IVA firm or chamberstrains by team: a disputes team in litigation and advocacy, a corporate team in corporate practice, with applied legal AI running through both, since every team uses it now.
VTalent and HRneed no track at all, only the level itself.
