Scotland suffered a whitewash in 2016, and were crushed 55-0 by France and 64-0 by England. The following year, they beat Wales and Italy at home, before last season’s first ever win in Ireland.
More recently, Munro’s side have suffered narrow warm-up defeats by the world’s fourth best side, Canada, and Spain, who are ninth.
“We’ve not won many games but we weren’t even in a position to compete before that,” said Munro of a period in which they went 35 games without winning.
“When I came into the job in 2015, the level of competition they faced didn’t prepare them for international rugby, so trying to get as many playing at a higher level on a weekly basis was the start of it.”
Eight players are now supported by Scottish Rugby contracts, while the likes of captain Lisa Thomson, Jade Konkel and Lisa Martin are playing at the highest level in England and France.
“When they go over they realise they aren’t superstars they’re playing against,” he said.
“Previously you didn’t get much exposure to French players, you see them on TV and think they are outstanding. But when you go and play with them you realise you’re just as good as they are.”
