===Competitive Grading=== |
|||
Competitive grading compares how well each bridge does against bridges built by other participants to determine a grade. The top scoring bridge is assigned a maximum numeric grade (say, 100%) while the lowest scoring bridge that still meets all basic specifications is assigned a minimum grade (say, 70%)<ref>[http://staff.hartdistrict.org/glyle/projects/bridge_project/index.html Canyon High School Balsa Bridge Competition]</ref>. |

The method guarantee that some scores will be high even if the overall quality of bridges is low. Conversely, it also guarantees that some scores will be low, even in situations where all bridges are of highyour |

===Standards-Based Grading=== |
|||
Standards-based grading sets certain standards that need to be met in order to earn a certain grade. An example of standards-based scoring would be to say that all bridges that hold 50 kg earn full credit; bridges that hold 25 kg earn half credit, and bridges that hold less than 10 kg earn no credit. |
|||
This method allows every bridge to potentially earn full credit if the standards are met. In situations where competition is weak, this method runs the risk of having many competitors receive no credit. |

The building of balsa-wood bridges is very often used as an educational activity. It may be accompanied by a larger project involving varying areas of study.
Typically classes which would include a balsa wood bridge cover the subject areas of physics, engineering, static equilibrium, or building trades, although it may be done independently of any of these subjects. Building a balsa wood bridge can be done after completing a section or unit covering a related topic or the process of design and building can be used to guide students to a better understanding of the desired subject area.
