Within a method for electrical testing a series of microelectronic fabrication die fabricated within a microelectronic fabrication substrate, there is first electrically tested the series of microelectronic fabrication die to determine at least one sub-series of electrically unacceptable microelectronic fabrication die. Similarly, there is also determined whether the microelectronic fabrication substrate may be reworked. Finally, there is also electrically retested only the at least one sub-series of electrically unacceptable microelectronic fabrication die, and only if the microelectronic substrate may be reworked. The method provides for enhanced efficiency when electrically testing the series of microelectronic fabrication die.
