For the past two years, we have been conducting a near-to-mid-infrared multiplicity survey of Class I and flat-spectrum young stellar objects (YSOs) in six nearby (d ⪉ 300 pc) dark clouds. The aim of our survey is to study the binary fractions and separations of Class I/flat-spectrum YSOs and diagnose the luminosities and evolutionary states of their components. Recent sub-arcsecond surveys of young stars have almost exclusively focused on pre-main-sequence T Tauri stars and have virtually ignored younger, Class I and flat-spectrum systems. Thus, we know very little about the multiplicity of self-embedded young stars. In this contribution, we present the results of our near-infrared survey of our six sample dark clouds.
