Teacher Enrichment in Computer Science (TECS) workshops are designed to provide quality pedagogically-oriented programs and resources in computer science for teachers of courses described in levels 2-4 of the model curriculum [1]. While those courses are (officially) recommended for grades 9-12, we recognize that some schools offer courses which cover some of the topics described in those levels to students in earlier grades, so the workshops might also be useful for teachers of those courses. In this document we use the phrase "secondary" to be inclusive of courses that cover material from levels 2 - 4 in the model curriculum.
