Abstract: This study reports on lessons learned from pre-service principals as they completed the Instructional Leadership Work Sample project and became instructional leaders. Data were collected from 150 participants over a four-semester time period. Teacher partners for the study were recruited from a variety of subject areas and from three organizational levels. Much has been written on instructional leadership over the past twenty years (Bossert, Dwyer, Rowan, & Lee, 1982; Cooper, 1989; Greenfield, 1987; Hallinger, 1990; Hallinger & Murphy, 1987; Heck, Larson, & Marcoulides, 1990; Sergiovanni, 2001). Initially, the construct caused consternation among practitioners and academics alike. In fact, one could argue that the field (professors of educational leadership and school administrators) initially rejected the idea of instructional leadership and thought of it more as the latest entry in a long list of designer-types of leadership--transformational leadership (Burns, 1978), credible leadership (Kouzes & Posner, 1993), quality leadership (Deming, 1997), creative leadership (Eisner, 1993), and situational leadership (Blanchard, Zigarmi, & Zigarmi, 1985)--or as an idea or activity that they did not have time for or that they thought to be clearly in the jurisdictional zone of teachers. Examples of this ambivalent thinking are portrayed in research conducted by Harchar and Hyle (1996, p. 21), who reported that some administrators believe there is no such thing as instructional leadership, while other administrators embrace the concept and argue that the role of instructional leadership must be in place. Teachers in this same study provide evidence for the construct of instructional leadership in its absence. One elementary teacher said that her principal was not an instructional leader because he did not have experience at the elementary level. She claimed he was a good manager of people, but could not understand the conversations that were occurring at the school level. Even scholars could not agree about the construct. While Harchar and Hyle (1996) reported that key elements of instructional leadership include establishing vision, developing trust, fostering collaboration, and demanding respect for all the school community, King (2002) argued that there is no litmus test for the presence of instructional leadership, nor is there a definitive list of its characteristics of behaviors. In places where instructional leadership truly exists, it becomes an integral, almost invisible, part of how a school community works, lives, and learns together. (p. 63) More recently, in the current wave of accountability and standards, instructional leadership is front and center in the preparation and professional development of principals (Leithwood, 2001; National Association of Elementary School Principals, 2001; National Policy board for Educational Administration, 2002; Sirotnik, 2002; Southern Regional Educational Board, 1998). State and national standards have been enacted and implemented in an attempt to improve student achievement and close the achievement gap (e.g., CSAP and NCLB). Since this legislation, responsibilities for principals have burgeoned to the extent that some fear the job can no longer be done by one person, or perhaps only by a fictional super-principal type (Copland, 2001). Lambert (2002) agreed and reported that "it has been a mistake to look to the principal alone for instructional leadership, when instructional leadership is everyone's work" (p. 40). Neuman and Simmons (2001, p. 9) proposed that in order for learning to become the focus and primary value for every member, leadership is the job of the entire education community, and must be distributed--one of the latest in the list of designer-leadership types. Even though literature about the origin, emergence, demise, and rebirth of instructional leadership abounds, little empirical research has been conducted on how pre-service principals learn about, acquire, and implement instructional leadership strategies and interventions that help teachers improve student achievement. …
