Student test scores and class ranks are converted to IL Standard Test Scores (ISTS) and IL Standard Rank Scores.  From those scores, an IL Weighted Selection Score (WSS) cutoff is determined by ISAC.  Students with an ISTS of 30 or higher (ACT score of 30 or better – Junior year only…the Feb. or April Test dates are used)  are automatically designated as State Scholars.  All other IL State scholars are eligible if they have a WSS that is greater than or equal to this year’s cutoff score of 48.  WSS is derived from adding the ISTS and ISRS (class rank) scores together.  The goal in mind is naming the top 10% of Senior Students in the State of Illinois.
