Building on its substantial and sustained evolution over the past thirty-plus years, Spanish for the Professions and Specific Purposes (SPSP) should flourish in the future as a paradigmatic curricular mainstay. A characteristic of its steadily emerging theory-based maturity within the Language for the Professions and Specific Purposes (LPSP) curricular ecosystem will be the increased thickness and granularity of SPSP in continual response to evolving learner needs. Development of SPSP as an adaptable signature feature of future Spanish curricula represents a fundamental, renewable long-term investment in the relevance, and therefore the centrality, of the study of Spanish. It is a commitment to curriculum development activism.
