I got very useful info from Quebec Immigration website, hope it is useful for you;
Below changes have been made since January 5, 2016
The first criterion changed is that of “Area of training.” This change ends the requirement by the Ministere for recent work experience related to the area of training for diplomas obtained more than five years ago. From now on, applicants will receive points for their diplomas regardless of when they were earned, provided that they were obtained before the application was submitted.
The second criterion changed is that of “Level of education.” This change will allow applicants to obtain points for this criterion provided that they obtained their diploma before their application was submitted.
