The 19-year-old made his debut in a 3-0 victory against Bradford in October and has started every Albion match since.
"Scott has done really well since he came here. He offers us more of an attacking option for the full-back position with his pace and athleticism," boss Paul Peschisolido told the club`s official website.
"He is a young lad with a really bright future. He had a spell out on loan at Southend last year but other than that he has just been playing reserve-team and academy football so far. It`s a big step up but he has performed well.
"I think there will be a certain amount of inconsistency but we need to be patient and I am really happy we will have him now until the end of the season."
