Many scientific programs envisaged for the space telescope (ST) require spectrophotometric observations with precise determimation of absolute flux as a function of wavelength. However, the accurate calibration of the ST instruments throughout the extremely broad (UV-IR) operational wavelength range presents a major challenge to the ST project. A program being carried out in collaboration with the ST calibration team, aims to provide accurate, absolute IUE spectrophotometric data for a number of faint standard stars with magnitudes near the limit of IUE's observing capability. The scope of the program and the precautions taken to maximize the accuracy of the IUE data are discussed.
