Item Lifecycle

QTI timeline Conceived in 1999, v1.0 released in 2000 Updated in 2001 (v1.1) and 2002 (v1.2) to improve and extend the model By 2003 it was clear that a major revision was necessary, a quick fix (1.2.1) was followed by a complete rewrite QTI v2.0 was published February 2005 QTI v2.1 (PD2) published June 2006 QTI v2.1 (Final) expected (early?) 2007
