If one is in a situation where a plan is mandatorily disaggregated for testing purposes into 2 plans (e.g. union and nonunion employees), then it is possible for only part of the plan to be a QACA. Other than those fairly limited circumstances, the plan document must specify the ADP/ACP testing method for the entire plan.

Thanks for the responses. The heart of my question is what does "arrangement" mean as used in "qualified automatic contribution arrangement"? For example, could a plan take the position that employees in Division A fall under a separate arrangement (i.e., the QACA) and employees in Division B are covered by another arrangement that is not a QACA. This would obviously be true if one was collectively bargained and the other wasn't, but what if both are not collectively bargained?
Judging from the response, it seems like the answer is "no." Can you provide me with a citation that says this or that otherwise defines "arrangment"? The reason I ask is that the 414 regs provide that not all individuals need to be covered by an EACA as long as the plan document specifies. I can't find anything that addresses this in 401(k)(13) or in the regs. Thanks!
