We show, by explicit calculation, that the next correction to the universal Luescher term in the effective string theories of Polchinski and Strominger is also universal. We find that to this order in inverse string-length, the ground-state energy as well as the excited-state energies are the same as those given by the Nambu-Goto string theory, the difference being that while the Nambu-Goto theory is inconsistent outside the critical dimension, the Polchinski-Strominger theory is by construction consistent for any space-time dimension. Our calculation explicitly avoids the use of any field redefinitions as they bring in many other issues that are likely to obscure the main points.
