Working memory is one of the most important skills children use every day, both in school and at home. It helps children remember information long enough to use it, solve problems, follow directions, and complete everyday tasks.
When working memory is weaker than expected, children may appear forgetful, distracted, or disorganized. Because these behaviors can also occur in ADHD and learning disorders, understanding working memory is an important part of a comprehensive evaluation.
What Is Working Memory?
Working memory is the ability to temporarily hold information in your mind while using it to complete a task.
Unlike long-term memory, which stores information for future recall, working memory is used in the moment.
For example, working memory allows a child to:
- remember a teacher’s multi-step instructions
- complete mental math problems
- keep track of ideas while reading
- organize thoughts while writing
- follow conversations
- solve complex problems
Children rely on working memory throughout the school day, often without realizing it.
What Does Working Memory Look Like in Everyday Life?
Working memory affects many everyday activities.
A child uses working memory when they:
- remember what needs to be packed in their backpack
- follow directions with several steps
- complete homework independently
- remember classroom instructions
- solve math problems without writing every step down
- participate in discussions
- keep track of information while reading
When working memory is working efficiently, these tasks often feel automatic.
Signs of Working Memory Difficulties
Children with weaker working memory may:
- frequently forget instructions
- lose track of what they are doing
- need directions repeated
- forget homework assignments
- struggle to complete multi-step tasks
- leave work unfinished
- lose their place while reading
- have difficulty remembering information they just learned
These behaviors are sometimes mistaken for carelessness or lack of effort, when they may actually reflect underlying cognitive challenges.
Working Memory and Reading Comprehension
Working memory plays an important role in reading.
As children read, they must remember information from earlier sentences while understanding new information.
Weak working memory can make it difficult to:
- follow longer passages
- understand complex stories
- remember important details
- connect ideas across paragraphs
- answer comprehension questions
Some children can read individual words accurately but still struggle to understand what they have read because holding multiple pieces of information in mind becomes difficult.
Working Memory and Mental Math
Working memory is also essential for mathematics.
Children use working memory to:
- solve mental math problems
- remember intermediate steps
- perform calculations
- compare numbers
- solve word problems
When working memory is limited, even students who understand mathematical concepts may find it difficult to complete more complex calculations efficiently.
Working Memory and ADHD
Working memory difficulties are common in children with ADHD.
Children with ADHD may have trouble:
- holding information in mind
- staying focused long enough to complete tasks
- organizing information
- following multi-step directions
- managing several pieces of information at once
However, not every child with weak working memory has ADHD.
Working memory challenges can occur alongside ADHD, but they may also be associated with learning disorders, anxiety, or other developmental differences.

Working Memory and Learning Disorders
Children with learning disorders may also experience working memory challenges.
Weak working memory can make it harder to:
- learn new reading skills
- organize written work
- solve math problems
- retain classroom instruction
- complete lengthy assignments
Because working memory influences many academic skills, comprehensive evaluations often examine it alongside reading, writing, mathematics, attention, and executive functioning.
How Is Working Memory Evaluated?
Working memory is typically assessed as part of a comprehensive psychological, psychoeducational, or neuropsychological evaluation.
Depending on the child’s needs, testing may include activities that measure the ability to:
- remember sequences
- manipulate information mentally
- solve problems while holding information in mind
- process increasingly complex information
Rather than relying on a single task, evaluators consider working memory alongside other cognitive abilities to better understand a child’s overall learning profile.

Can Working Memory Be Improved?
Many children benefit from strategies that reduce the demands placed on working memory.
Examples include:
- breaking large tasks into smaller steps
- providing written directions
- using visual reminders
- creating consistent routines
- teaching organizational strategies
- allowing additional processing time when appropriate
The most effective supports depend on the child’s individual strengths and challenges.
When Should Parents Consider an Evaluation?
Parents may wish to consider a comprehensive evaluation if their child consistently experiences:
- difficulty following directions
- forgetfulness
- attention problems
- reading comprehension struggles
- math difficulties
- organization problems
- inconsistent school performance
An evaluation can help determine whether working memory difficulties are related to ADHD, learning disorders, executive functioning challenges, or another developmental concern.

Final Thoughts
Working memory is one of the brain’s most important cognitive skills. It supports learning, attention, reading comprehension, problem solving, and everyday classroom performance. When working memory is weaker than expected, children may struggle with school even when they are bright and motivated.
Because working memory challenges can overlap with ADHD, learning disorders, anxiety, and other developmental conditions, a comprehensive evaluation can help identify the underlying factors affecting a child’s learning and provide recommendations that support long-term academic success.
