In order to allocate education resources reasonably in high school, coordinate the contradiction which load and load capacity in high school was not match, it redefineed resources system load in high school, discussed the nature dynamic load and characters of impact load and bearing capacity of resources system in high school. As the example of Hunan University of Science and Technology, it rendered scientific prediction and calculation for the load of resources system in high school. The results show that resources system load calculation program in high school make scientific prediction for load of system in high school, which provide decision-making basis for rational allocation of resources in high school.
