She goes to her dancing class twice a week.

[Silverobama]

One of my students told me she's learning how to dance now and goes to her class twice a week.

Is the sentence "She goes to her dancing class twice a week" to describe her going to the class to learn how to dace?

Yes. You could also say:

She takes dancing lessons twice a week.

In BrE, it's more common to refer to them as "dance classes" rather than "dancing classes".
