An engineering graphics literacy assessment for constraint-based modelling course was developed and tested by a visiting Fulbright Scholar at North Carolina State University (NCSU), USA. Later the students from Latvia University of Agriculture (LUA) and from two sections at Riga Technical University (RTU) in Latvia participated in an experiment to test this methodology. All the 75 students from three universities were asked to create 3D models for seven parts given in an assembly drawing of a mechanical device within two hours’ time period. The parts in the assembly ranged in complexity from a simple ball to a complex valve body. Students were given a ruler to measure parts on the B-size third quadrant or A3 size first quadrant drawing and determine sizes of geometric elements based on the given scale (2:1). It was difficult to compare the test scores on the modelling assessment and other measures in the course (final project, final exam, and final course average) because universities have different grading system. This paper summarizes how students performed (number of parts modelled, scores, total time, etc.) on the developed Riga-Raleigh Test (named after the cities where it was inspected at first), reports analyses of relationships between their scores on the assessment and other measures in the course, and also presents ideas for future studies.
