The Block Kids Building program is a national building program competition that is sponsored on the local level by NAWIC chapters and other organizations. The award-winning program introduces children to the construction industry to create an awareness of and to promote an interest in future careers in one of the many facets of the industry. The program is open to all elementary school children in grades K-6. The competition involves the construction of various structures with interlocking blocks and three of the following items: a small rock, string, foil, and poster board. Local winners advance to the Regional Competition and one semi-finalist from each region is entered in the National Program Competition. National prizes are awarded to the top three projects.
