Thanks, Elizabeth, and Matt for asking the question.
I would definitely transition to the 2019 framework, even though the 2009 framework is still fundamentally sound.
As Barbara writes, the 2009 framework was reimagined in 2019 “to adapt to the changing information, education, and technology environments, as well as the increasing diversity in our student populations”. Furthermore:
The re-imagined ESIFC includes increased or new attention to pre-kindergarten, multiple literacies, digital citizenship and civic responsibility, multiple perspectives, personalization of learning, design thinking, student voice and agency, and social and emotional growth. Different sections provide a PK-12 continuum of skills, identification of priority skills for every grade level, and graphic organizer assessments for the priority skills.
I am hopeful that I will soon be able to write about this more fully, because Blanchelande College is a PK-12 school and have begun to think more purposefully about how to align each phase of the school with the 2019 framework.
I will also flag this question / topic with Barbara, who, as originator of both frameworks, will be best placed to shed light on the intention for their use.
