A natural progression from the authors' widely known work on assessment and programming in early intervention, LINK is a revolutionary process that hurdles traditional obstacles to selecting and using authentic assessment-intervention-evaluation procedures for young children. Pulling the best properties from well-known assessment and curriculum models, LINK identifies critical markers for judging quality and effectiveness: authenticity, collaboration, convergence, equity, sensitivity, and congruence. The authors apply this unique six-standard index to more than 50 different curriculum-embedded and curriculum-compatible assessment and intervention systems, rating and analyzing each. In addition, they explain how early childhood professionals can perform their own quality reviews and then customize the system(s) of their choice to specific populations or programs. With this essential resource in hand, early intervention team members and administrators can ensure the individualized support opportunities every child needs for healthy deyelopment.
