The problem of obtaining A optimal designs for comparing v test treatments with a control in b blocks of size k each is considered. A step type design is a BTIB design in which the control is replicated t times in some blocks and t 1 times in the remaining blocks. A condition on the parameters v,b,k is identified for which optimal step type designs can be obtained. Families of such designs are given. Methods for searching for highly efficient designs are proposed, for situations where it is difficult to determine an A optimal design.
