Intended for the front-line practitioner, this toolkit provides tips, options, and practical how-tos for designing and implementing quality, youth-focused, and business-focused services for out-of-school youth (OSY) who are currently in, or about to enter, the workforce. It outlines an "income growth strategy" (IGS) that addresses what services should be delivered and how, when, and where to deliver services. Section 1 discusses the need for highly skilled workers and balancing 'work first' and retention/advancement goals. Section 2 addresses what an IGS does and why it should be considered, including youth development as the central theme; incorporation of a broader perspective; and balancing needs and wants. Section 3 focuses on these considerations when designing an IGS: applying the key principles of income growth; four design principles for IGS; income goal versus job placement goal; accommodate working individuals; just-in-time service intervention; solving problems in context; and four frameworks for income growth and post-employment services. Section 4 describes eight ways to make an IGS happen. Section 5 discusses how the IGS complements the Workforce Investment Act of 1998. Section 6 addresses special considerations for the business customer. Section 7 describes how the toolkit was developed. Appendixes include a list of nine Web sites and eight annotations of reports and resources and a service matrix. (YLB)
