Example of Bloom's Taxonomy

Training levels have been added to the following adaptation of Bloom's taxonomy to corrosion education, with Level 1 corresponding to the easiest goal and level 5 to the most difficult. Typically, goals belonging to levels 4 and 5 would be required of students in their last years of an engineering program, or at the graduate level. Levels 1 to 3 would correspond to difficulties associated with the very first years of any university program.
