What do the IXL Real-Time Diagnostic levels mean? ›

A student's diagnostic level represents their working grade level. So a level of 400 represents a readiness to start working on 4th-grade skills, and a level of 450 means the student is about halfway through the 4th-grade curriculum.

IXL Diagnostic scores are scaled such that scores correspond to grade levels. For example, a score of 350 indicates that the student has acquired about 50% of third-grade material, whereas a score of 400 indicates that the student is ready to learn fourth-grade material.

An IXL Diagnostic level of 500 represents readiness to begin working on fifth-grade level skills. When a level is displayed as a circle with a star in it, your exact level has been revealed!

IXL's diagnostic scores correspond to grade levels for easy interpretation. For example, a score of 500 equals beginning level 5th grade, and a 550 equals 50% mastery of 5th grade standards.

Grade level guide: 100 = 1st grade, 200 = 2nd grade, 300 = 3rd grade, 400 - 4th grade, 500 = 5th grade, 600 = 6th grade, 700 = 7th grade, 800 = 8th grade, and 900 = 9th grade. By clicking on the IXL image above or the word IXL, students will be forwarded to the log in page.

The Real-Time Diagnostic is always available; students can enter the Diagnostic at any time and answer as many questions as they like. When students first use the Diagnostic, we recommend they aim to diagnose until their complete diagnostic data is revealed—for most students, this will be around 45 minutes per subject.

*Note: Diagnostic levels correspond to grade levels. For example, a score of 850 indicates the student understands about 50 percent of 8th grade material. Pro Tip: Use these scores to determine whether your students are working above, at, or below grade level, and how many students are at each level.

For example, a score of 350 indicates that a student understands about 50% of 3rd-grade material and a score of 400 indicates readiness to begin working on 4th-grade skills. These levels range from 0-1300, with 0-50 representing pre-K, 50-100 kindergarten, and 1300 representing the end of 12th grade.

Fourth grade is displayed as Level F.

IXL diagnostic numbers represent where students are in terms of grade levels. A level of 740 represents a student having learned 40% of the 7th grade skills.

How long until IXL pauses? ›

Depending on your student's grade level, it will take two, four, or six minutes of inactivity for the timer to pause. What exactly is the SmartScore? The SmartScore is based on IXL's proprietary algorithm and is the best possible measure of how well a student understands a skill.

Validity research shows that IXL's Diagnostic is an accurate measure of student achievement and a strong predictor of performance on standardized assessments including NWEA MAP, Star, FAST/B.E.S.T., PSSA, and over a dozen other state assessments.

A student's diagnostic level represents their working grade level. So a level of 400 represents a readiness to start working on 4th-grade skills, and a level of 450 means the student is about halfway through the 4th-grade curriculum.

IXL's Diagnostic uses a continuous vertical scale across grades PreK-12 ranging from 0 to 1300, indicating grade-level proficiency. By contrast, SOL scores range from 0 to 600 within each grade, with 400 being the proficiency cutoff.

Diagnostic levels correspond to a student's overall working grade level. For example, a 300 shows that a student is beginning to work on 3rd grade material, whereas a 370 shows they are about 70% through the 3rd grade curriculum, and so on.

Students will need to answer as many as 10 questions correctly in a row to achieve mastery. For most skills on IXL, students will have to complete a minimum of 28 questions to earn a SmartScore of 100.

A student's diagnostic level represents their working grade level. So a level of 400 represents a readiness to start working on 4th-grade skills, and a level of 450 means the student is about halfway through the 4th-grade curriculum.

Fifth grade is displayed as Level G.

Address foundational reading gaps with IXL's day-by-day skill plans! Level 1 teaches phonological awareness, letter-sound associations, CVC words, blends and digraphs, and high-frequency words. By the end, students can read simple sentences with short vowel words. How many syllables does the word have?

Researchers found that the IXL Real-Time Diagnostic demonstrates high reliability as a measure of math and ELA achievement. Additionally, IXL's diagnostic is a good predictor of performance (using ILEARN as a criterion measure), with a correlation of . 90 in math and . 86 in ELA.
