Ilr after 6yrs discretionary leave

My wife is coming to the end of her six years of discretionary leave.Iam British which form do I fill in for ilr and is she exempt from life in the uk test?

Application for Indefinite Leave to Remain is made using Application Form DL after six years of DL.

if you were granted discretionary leave to remain following refusal of your asylum claim and in any other case the Application Form SET (O) will be used to apply for Indefinite Leave to Remain (ILR).

On exemption read here; Refugees and those with humanitarian will continue to be exempt from the
requirement in recognition of their continued need for protection. For the present we will
continue to exempt those granted discretionary leave (DL), although we will consider this
further and keep this position under review.
