The experts form the assessment commission, which specifies the assessment criteria on the basis of the task.

Assessment criteria are e.g.:

• Clarity and precision of the construction
• Neatness and clarity of the scribed timber
• Neatness of the workmanship (cuts, deburring, joints)
• Dimension precision and accuracy of fit (+/- 1 mm)
• General impression

The assessment of the submitted roof truss models takes place in accordance with the criteria and the factors listed in the Competition Rules, Clause A 6.2. Competition Rules can be downloaded here.

Each individual assessment will be judged according to a ten-point key, whereby ten points for a perfect achievement and one point for a completely insufficient achievement are given. The total points are divided by the number of experts and multiplied by the factor.

A competitor can exchange timber or perform re-working cuts for use of material. Points are taken off for new timber or re-working cuts.

The results of the two best competitors of each nation shall be used for the ranking of nations.
