Language Test requirement when renewing BRP

[RH_Colo]

Hello,
Apologies if this is covered in another topic, but couldn't quite find what I was looking for.

My wife currently has a BRP which expires in August 2018. In order to renew, I believe I have to use this form: https://www.gov.uk/uk-family-visa/partner-spouse

As part of her original visa application showing Knowledge of English, we submitted my wife's IELTS certificate which had been accepted. However, this certificate was only valid for 2 years (expires June 2018). As part of the renewal process, will my wife have to take/pass another English knowledge test?

Kind regards,
Richard

FLR(M) is the correct form.

A2 English is required for extensions since May 2017.
