Margo Gottlieb, Ph.D., is a staunch advocate for multilingual learners and their teachers. As co-founder and lead developer of WIDA at the University of Wisconsin-Madison in 2003, Margo has helped design and contributed to all the editions of WIDA’s English and Spanish language development standards frameworks and their derivative products. Being a bilingual teacher, facilitator, consultant, and mentor across K-20 settings, she has worked with universities, organizations, governments, states, school districts, networks, and schools in co-constructing linguistic and culturally sustainable curriculum and reconceptualizing classroom assessment policy and practice.
Margo’s passion has always been assessment in its many forms, starting with her dissertation, a K-12 multilingual test in Spanish, Lao, and English that integrated content and language. Since then, she was appointed to national and state advisory boards, served as a Fulbright Senior Scholar, and was honored by the TESOL International Association in 2016 for her significant contribution to the field. In her travels, Margo has enjoyed keynoting and presenting across the United States and in 25 countries. Having authored, co-authored, or co-edited over 100 publications, including 20 books and guides, Margo's 3rd edition of her best-selling book, Assessing Multilingual Learners: Bridges to Empowerment, is the latest addition to her Corwin compendium.
