			The four OWLS-II scales &mdash; Listening Comprehension (LC), Oral Expression (OE), Reading Comprehension (RC), and Written Expression (WE) &mdash; give a complete, accurate, and useful picture of language skills.

			<h3>Benefits</h3>

			<ul>
				<li>Identify students with learning disabilities, language disorders, and related difficulties in accordance with IDEA requirements.</li>
				<li>Design targeted interventions that address potential academic difficulties.</li>
				<li>Monitor progress, using the new alternate form.</li>
				<li>Gather longitudinal data for research purposes.</li>
			</ul>

			<h3>Features</h3>

			The LC and OE Scales assess receptive and expressive language. The WE Scale measures the expressive aspects of written language. The RC Scale measures the receptive aspects of written language and is uniquely effective in identifying language factors that may be impairing or facilitating reading comprehension.&nbsp;

			Each of the four scales assesses four linguistic structures:

			<ul>
				<li>Lexical/Semantics</li>
				<li>Syntax</li>
				<li>Pragmatics</li>
				<li>Supralinguistics</li>
			</ul>

			You must have Windows XP SP3 or Macintosh OS 10.4 to run the OWLS-II scoring software.

			Please note: Apple discontinued support for Coco causing these programs to stop working after 10.5
