We analyze the relationship between the stellar accretion rate and the disk mass in 32 intermediate-mass Herbig Ae/Be systems and compare them to their lower-mass counterparts, T Tauri stars. We find that the $\\dot{M}$--$M_{\\rm{disk}}$ relationship for Herbig Ae/Be stars is largely flat at $\\sim$10$^{-7}$ M$_{\\odot}$ yr$^{-1}$ across over three orders of magnitude in dust mass.
