Lightspan’s Suite of Products Selected by Illinois School District for Assessment, Professional Development and Student Achievement

December 4, 2002

Carol Sossong, Assistant Superintendent for Curriculum and Instruction,

said: “After careful consideration, we chose to build upon our existing relationship with Lightspan. Our district has used The Lightspan Network since 1999 in 20 of our schools and it’s been a wonderful tool for teachers, parents and students. Adding Lightspan eduTest Assessment to all of our district’s schools will provide our teachers with vital, real-time data on student achievement. This is especially important with the new emphasis on accountability in the No Child Left Behind Act.”

The Joliet Public Schools District 86 will add the following Lightspan

products:

— The Lightspan Network has been renewed for three years and will be

implemented in all 21 of the district’s schools. The Lightspan

Network is a suite of tools and resources that helps simplify

instructional planning and supports ongoing professional growth. This

includes management and communication tools that bring teachers

together, and a variety of curriculum and learning activities that

promote student achievement. All of these features are designed to

help streamline the process of aligning and organizing curriculum to

state standards and assessment.

— Lightspan eduTest Assessment will be implemented in all 21 of the

district’s schools over the next three years. Lightspan eduTest

Assessment is a comprehensive online accountability and assessment

program that lets educators quickly identify district, school, class,

and student strengths and needs relating to state and national

standards.

— Lightspan Achieve Now will be implemented in two of the district’s

schools and will include a home deployment component to extend

learning to the home and help increase family involvement in students’

learning. Lightspan Achieve Now is a standards-based curriculum

program used by students in kindergarten through eighth grade that is

proven to increase student achievement in reading, language arts, and

mathematics.

We share the district’s commitment to help increase academic achievement for all of its students by providing high-quality, research-based educational resources and a strong commitment to professional development.”
