SDL (self-directed learning) now is offered as an alternative form for learning and teaching approach. SDL initially has developed in the field of adult learning. The question that may rise is whether SDL is applicable for younger ages. This study intended to generate a reliable and valid translation of a recently released instrument to measure SDL readiness (SDLRS-ABE) among children from nine to 11 years old and explore the quality of SDL among children of Tehran city through the translated instrument. The results indicated that SDL among children is measurable, the translated version of SDLRS-ABE is reliable (Alpha Cronbach estimated as 0.808), the validity of the Persian version was ascertained by the author of original scale, the characteristics are same to adults, children are able to learn on their own and schools' system does not give room to children to actualize their ability to perform learning on their own.
