How can I use "which is required for" in a sentence?

Use "which is required for" to add a nonrestrictive clause that provides essential information about a noun. For instance, "The G.R.E., "which is required for" most graduate programs, tests reasoning skills."

What are some alternatives to "which is required for"?

Alternatives include "that is necessary for", "that is essential for", or "that is needed for". Choose the phrasing that best fits the context and desired level of formality. See more at: "that is necessary for", "that is essential for".

Is it better to use "that" or "which" in "something that/which is required for"?

While both "that" and "which" can introduce relative clauses, "which" is preferred for nonrestrictive clauses that add extra information. "That" is generally used for restrictive clauses that are essential to the meaning of the sentence. Since ""which is required for"" often introduces extra info, "which" is more suitable.
