Management of educational building assets is one of the most complicated factors because it has a bigger number of related and unrelated criterions. Analytic hierarchy process (AHP) as a decision-making technique is widely deal with many decision problems that have bigger number of criterions. This paper proposes AHP method to define the judgment matrix of related and unrelated criterions that is used to calculate the relative weights (RWs) of each criterion. Analytic network process (ANP) was also used to calculate the RWs of the interrelated building categories (architectural, mechanical, and electrical). Such RWs can be used by managers for physical condition assessment of an educational building. The educational building hierarchy are divided into five levels. Each level is then defined in a judgment matrix to calculate its RWs. Then. The consistency of such judgment matrix has been evaluated to ensure that the RWs' results are acceptable. As concluded in the space level of the building hierarchy, the classroom space type that includes most of the education processes had the highest relative weight (RW=26.76%) followed by the bathrooms (RW=26.14%) and corridors and stairs (RW=25.77%). On the other hand, the cafeteria space type was the least relative weight (RW=1.58%) among all other space types. AHP technique provided an improved approach to calculate the RWs of each criterion affecting physical condition of educational building in Egypt.
