comprehensive guide to literacy assessment

Literacy—the ability to create, consume, and critique different types of multimodal text—starts with building foundational reading skills and identifying instructional needs through literacy assessments.

The significance of literacy assessments

Literacy assessments are important because they help educators identify what students need to focus on so they can become stronger readers²—but they’re not one-size-fits-all. Each type of literacy assessment can broadly or specifically identify student skill gaps within reading. Some assessments end at that point, while others provide further intervention opportunities. But it’s important to note that assessments are not just about diagnosing skill gaps. They also help teachers identify students who need enrichment and extension intervention.

Types of literacy assessments

There are three common types of literacy assessments: screening, diagnostics, and progress monitoring. The diagnostic reading assessments each have different goals and periods for evaluation.

Screening assessment

A screening assessment, also known as a universal screener, is a broader assessment that helps teachers identify students’ strengths and weaknesses. It also pinpoints those who are not meeting grade-level learning goals, checks for warning signs, and provides valuable insights to teachers so they can help struggling learners now or in the future.

From a school or district standpoint, a universal screener can confirm whether or not their literacy curriculum is effective in helping students understand the concepts.

How to apply screening assessments

A screening assessment is the critical first step in determining the scope of reading support needed by the school and is administered to the entire student population³ usually three times per year. According to the National Center for Improving Literacy (NSLI), the core elements of screening assessments should be brief, easy to administer, valid and reliable, timely, and informative.

Further examples of how to apply screening assessments include naming sounds in spoken words (phonemes) and sounds or names of letters in kindergarten and reading words in brief passages in first grade.

Progress monitoring

Progress monitoring is a formative assessment that confirms whether the additional support or intervention is or is not successful. It also allows the educator to make changes at various points during the school year and determine if students can catch up to their peers. This type of assessment should be skill-based but sensitive enough to show growth over a short period. There are two types of progress monitoring:

Progress monitoring tools

Progress monitoring tools measure a student’s progress throughout instruction and intervention. They may be given weekly, bi-weekly, or monthly, depending on the intensity of intervention and needs of the student. Progress monitoring tools report the student’s growth in reading and help the teacher to adjust instruction.

  • Mastery measurement: Evaluate performance on one specific skill to ensure mastery before moving on to the other
  • General outcome measurement: Effective means of tracking progress throughout the entire curriculum by evaluating frequently, either through curricular sampling (every skill evaluated) or performance indicators (student scores indicate performance)

How to administer progress monitoring assessments

Progress monitoring occurs every 1-3 weeks. A general example includes weekly oral reading fluency tests to measure student reading progress throughout the entire year. This can include tracking the number of works students can correctly read per minute by doing timed repeated readings. The progress can be checked week-over-week to see how the student’s reading skills are improving.

Diagnostic assessments 

Diagnostic assessments identify a student’s specific strengths and weaknesses in reading, for example, phonics or vocabulary skills. Diagnostic tests provide a detailed profile of the student’s needs to guide intervention. Diagnostic tests are given after a student fails a screener and may be repeated as often as needed by the teacher to find out more about the student’s reading skills.   Diagnostic assessments identify specific areas where students are performing and provide more detailed information on where they need help. This type of assessment is usually not administered to the entire student population.

This type of assessment can be formal or informal and includes:

  • Assessments that help pinpoint specific skill gaps
  • End of unit tests to check for understanding
  • Once identified, the information is used to narrow down a targeted support or intervention to help the student improve.

General examples include components of literacy subtests:

  • Word recognition
  • Decoding
  • Reading comprehension
  • Spoken and written language

Summative assessments 

Summative assessments are used to evaluate student performance at the end of an instructional period or school year. Two examples of summative assessments could be an end of unit test for a grade’s reading program or taking a state’s required reading test. Summative tests measure a student’s overall reading performance and effectiveness of the school’s reading program.  

Understanding reading assessments

Effective assessments must identify student skill needs/gaps and diagnose the help they need. Two principles are standards and validity. For standards, literacy assessment must align with established state educational standards. It’s also important to clearly define learning objectives and outcomes to measure. Valid assessments⁵ produce data that can be used to inform education decisions like school effectiveness, teacher evaluation, and individual student performance and gains. It incorporates the assembling of evidence to support test score interpretation based on the desired measured construct. The ultimate goal is to determine if the assessment measures what it’s supposed to measure.

Assessment methods

Assessments are completed in person through a physical assessment or digital format. Each assessment addresses components of a student’s ability to recognize sounds and letters, read accurately, and comprehend vocabulary and text passages.

Phonics and phonemic awareness assessments

A phonics assessment is a diagnostic tool that gauges a student’s ability to recognize letter sound patterns, as well as blend sounds together to decode words.

Phonemic awareness assessments measure the ability to hear and manipulate the sounds in spoken words. It also includes the understanding that spoken words and syllables are made up of sequences of speech sounds, or phonemes.

Strengths of phonics and phonemic awareness assessments

Phonics assessments help identify areas where a student may struggle such as decoding skills, letter-sound relationships, or blending sounds. An example of this are the pre-tests and end-of-unit assessments in the 95 Phonics Core ProgramⓇ .  Additionally, phonics assessments like the 95 Phonics Screener for Intervention, helps to pinpoint the skills that each student has mastered and those that still need additional instruction. This assessment maps direction to phonics skill lessons in the 95 Phonics Lesson Library™—a Tier 2 intervention program that provides 75 evidence-based, fully prepared phonics lessons ranging from basic to advanced to multi-syllable skills.

Strengthening phonemic awareness skills is crucial for reading. Identifying these learning gaps early gives the student time to learn and catch up on their sound skills. Student assessment results can provide educators with opportunities to tailor their instructional strategies to those that target a student’s phonemic awareness weakness.

Both phonemic awareness and phonics assessment results can help tailor and guide adjustments to instruction to better meet the needs of students.

Weaknesses of phonics and phonemic awareness assessments

Phonemic awareness assessments do not completely depict a student’s overall reading abilities. For some phonemic awareness assessments, students whose primary language isn’t English may be affected, so it’s important to consider cultural contexts.

Phonics assessments’ narrow focus on isolated skills could risk overlooking a student’s comprehension and language abilities. Generally speaking, administering phonics assessments may also take some time.

Oral reading fluency assessments

Oral reading fluency (ORF) assessments measure reading rate and accuracy. This is usually measured as words read correctly per minute. Three components of oral reading fluency are accuracy, rate, and expression.

Strengths of oral reading fluency 

ORF can be smaller, quicker, and less expensive compared to major assessments⁶. It can also quickly determine results and catch children who are struggling to read. ORF is not restricted to school systems, so parents can also participate to fill in the gaps.

Weaknesses of oral reading fluency

One of the weaknesses of ORF is that it is not comparable across countries or languages and can require significant resources and time. Some students have become adept at decoding words but because of the outsized capacity it takes for them to do so, they can’t attend to the meaning. This can be hard to pick up on from an ORF unless you are also employing a retell of the story.  Additionally, its accessibility to everyone could run the risk of not administering the assessment correctly or coming to the wrong conclusions.

Vocabulary assessments

Vocabulary assessments are evaluations of a student’s knowledge of vocabulary words. This includes the size of their word knowledge, their ability to comprehend word meaning, and their capacity to use words effectively.

Strengths of vocabulary assessments

Vocabulary assessments can lay the groundwork for strengthening reading and writing skills and contribute to cognitive development by promoting memory, categorization, and word association. This assessment also gauges a student’s ability to communicate verbally and understand spoken language.

Weaknesses of vocabulary assessments

Weaknesses of vocabulary assessments include that it’s not representative of linguistic competence⁷ involved in everyday tasks. It’s also not representative of children’s true expressive language abilities, resulting in students not receiving proper intervention.

Comprehension assessments

A reading comprehension⁸ assessment asks a student to read a passage of text, followed by detailed questions about the content of the text.

Strengths of comprehension assessments

Reading comprehension assessments can help identify specific areas of strength and weakness in a student’s comprehension. Ongoing assessments can serve as progress monitoring to further evaluate overall effectiveness, improvements, and areas that need additional support. These types of assessments also help students familiarize themselves with the types of questions they’ll encounter on standardized tests.

Weaknesses of comprehension assessments 

One weakness of reading comprehension assessments is that they may not fully reflect a student’s ability to comprehend different genres or topics. This could be influenced by test-taking skills vs. actual comprehension, which can result in potentially incorporating cultural biases that could disadvantage students from diverse backgrounds.

Using assessments to improve literacy instruction

The role of literacy assessments is to provide teachers with information regarding the next steps in the learning progression⁹. Assessments are integral in informing educators on how to tailor their instruction while learning is in progress. Assessments can be formative or summative.

The goal of formative assessments is to monitor student learning and provide ongoing feedback. They’re usually lower-stakes assessments that help students identify their strengths, weaknesses, and additional areas of improvement. For educators, it helps them monitor the progress of student performance and continue to address learning gaps.

Summative assessments evaluate student learning at the end of instruction by comparing it against a benchmark. This is usually a higher-stakes assessment, such as a standardized test.

Final word

To summarize, literacy assessments are crucial in promoting literacy development since they help educators and school districts identify students’ strengths and weaknesses. Screening, diagnostics, and progress monitoring serve distinct purposes in providing valuable insights for tailored instruction. Together, phonemic awareness, phonics, oral reading fluency, vocabulary, and comprehension assessment methods can accurately provide a holistic picture of student reading skills.
