There is no clear-cut division between orality and literacy (Street, 1993). This idea is central to literacy development in the Spanish heritage language (SHL) context because the opportunities to use heritage language (HL) skills are often oral, not written. Furthermore, the cultural situations that speakers find for their language are less extensive since they are in an environment where their HL is not the dominant language. This paper surveys the research on the writing of SHL learners (SHLLs) and proposes an integrated approach of product, process and post-process writing within a critical pedagogy that allows SHL writers to own the development of their HL literacy.
