While engagement programs are often episodic or separate from an art organization's core programming, in late 2013 a group of 10 arts nonprofits across California set out to make engagement central to their work. They aimed to transform their programmatic, organizational, and business models in ways that would improve and sustain their reach and relevance to ethnically diverse or low-income Californians. The organizations--a mix of museums, theater groups, multidisciplinary arts centers and presenters, and symphony orchestras--received three-year grants, totaling $8.9 million, as partners in the New California Arts Fund (NCAF) of The James Irvine Foundation. This document summarizes findings and implications identified by Slover Linett Audience Research in a 2017 evaluation of these NCAF grantee-partners. [For the full report, see ED604062. The James Irvine Foundation commissioned Slover Linett Audience Research to design and conduct a multi-method evaluation of the NCAF experience of the initial 10 grantee-partners during the first three years of their participation in this initiative.]
