improve one's communication level

[Eric001]

Hi, everyone there

What is the best word to say " improve one's communication level"? Can we say " boost one's level, enhance one's level or uplift one's level"? Thank you

[Marius Hancu]

improve his communication skills
raise the level of his communication skills

are neutral and appropriate for business. Boost is making too much of it, too pompous.

As a matter of fact, what I want to know is what is the appropriate words to use with "level" to express "make one's level higher"? Thank you.

[Marius Hancu]

raise his level
elevate his level
