One of the important differences between previous educational qualifications (and the earlier grading of A-levels) and the later GCSE qualifications was supposed to be a move from norm-referenced marking to criterion-referenced marking.  On a norm-referenced grading system, fixed percentages of candidates achieve each grade. With criterion-referenced grades, in theory, all candidates who achieve the criteria can achieve the grade. A comparison of a clearly norm-referenced assessment, such as the NFER Cognitive Ability Test or CAT, with GCSE grading seems to show an unexpected correlation, which challenges the idea that the GCSE is a properly criterion-based assessment. 
Civil engineering and Building Information Modeling (BIM) are among the hottest drafting specialties, projected to grow more than twice as fast as the overall drafting field. Increased construction activity stemming from . population growth and the need to improve America’s infrastructure will spur demand for AutoCAD drafters who are trained and certified in Civil Drafting, BIM and interior design. Product Data Management (PDM) software - programs that track and control data related to a specific product and its lifecycle, including CAD schematics - is another emerging drafting domain that's stirring up workforce buzz and demand.
