Signs By Stage: High School

Signs Of Dyslexia In Teens: A High School Checklist

The signs and symptoms of dyslexia in teens are slow, effortful reading, spelling that stays weak under time pressure, and written work that falls well short of what the student can say out loud. Many of these students coped in primary school, and the difficulty only shows when the reading and writing load rises in Years 7 to 10.

Checklist: Signs Of Dyslexia In High School Students

No single sign means dyslexia. Look for several signs together, in a student who has been taught well and is trying. Each sign below comes with the reason it happens.

Reading

  • Stalls on subject words, or skips them. Words such as “photosynthesis” or “parliamentary” have to be sounded out, and sounding out is the weak point.
  • Understands far more when the text is read to them. Listening is not the problem. Getting the words off the page is.
  • Needs two or three passes to get through a chapter. Working out the words takes so much effort that little attention is left for the meaning.
  • Avoids reading aloud, or trips on short common words as well as long new ones. Reading aloud cannot be hidden. Words that are not yet automatic have to be worked out on the spot.
  • Rarely reads by choice. Reading has always cost more effort than it gives back.

Spelling And Writing

  • Notes from class are thin or unfinished. Listening, deciding what matters and spelling it, all at once, is too much to do at speed.
  • A timed in-class essay reads far below their homework. Under time pressure there is no room to check each word, so spelling and sentences both slip.
  • Writes much less than they know. Spelling and getting sentences down use up the effort that planning an essay needs.
  • Swaps the word they meant for one they can spell. A student who says “inevitable” in class discussion will write “sure to happen” in the essay.
  • “Photosynthesis” in the question, a different spelling in the answer. Even with the word printed on the test paper, the spelling was never stored firmly, so it is rebuilt from its sounds.

Speaking And Remembering

  • Mispronounces long words or mixes up words that sound alike. The sound pattern of a new word is stored loosely.
  • Loses track of a string of instructions. Many students with dyslexia also have a weaker working memory, and healthdirect notes this can show more as school asks more.
  • Finds a second language unusually hard. A new language means learning a new set of sounds and spellings, which is the same skill that makes English reading hard.

Time And Effort

  • Homework takes far longer than it does for classmates. Reading and writing are slower at every step.
  • Runs out of time in tests. Reading the questions uses up the minutes.
  • Marks do not match the effort or the understanding shown in class. School reports say things like “capable, needs to try harder”.
  • Tired, flat or anxious about school, or avoiding certain subjects. Years of working harder for less wear a student down.

If You Are The Teenager: Does This Sound Like You?

  • I read the same page several times before it goes in.
  • I know what I want to say, but it comes out shorter and simpler when I write it.
  • I pick a different word because I cannot spell the one I mean.
  • I dread being asked to read aloud.
  • I run out of time in tests even when I know the work.
  • If there is a video or a podcast on it, I go to that first.
  • I spend longer on homework than my friends and get lower marks.
  • Some days school makes me feel slower than everyone else.

If most of these sound like you, it is worth showing this page to a parent or a teacher you trust. Dyslexia has nothing to do with how smart a person is.

How To Read The Checklist

A checklist cannot tell you whether a teenager has dyslexia. It can tell you whether an assessment is worth arranging. Three things make the signs more likely to matter:

  • There is a cluster. Several signs across reading, spelling and writing, not one or two.
  • They are not new. Looking back, reading and spelling were hard work in primary school too, even if the marks were fine.
  • They have lasted. The difficulty is still there after good teaching or extra help.

A family history adds weight: dyslexia tends to run in families, so a parent, brother or sister with reading or spelling difficulties makes the signs more likely to matter. Poor attention, missed schooling, hearing or vision problems and anxiety can produce some of the same signs, which is why a list is a starting point and not an answer. Attention is the most common look-alike, covered in ADHD and dyslexia. The signs at every stage are on the signs of dyslexia page.

Why it is missed

Why Dyslexia Can Go Unnoticed Until High School

Dyslexia does not begin in the teenage years. It is there from the start, and some students cover it for a long time. A bright child with a good memory can learn enough words by sight, pick up the rest from context and get through primary school on effort. Raising Children Network notes that older children can become quite good at covering up problems with learning, and healthdirect says dyslexia is often not picked up in the early years of school.

High school removes the cover. From Year 7 there are more subjects, each with its own vocabulary, longer texts to read alone, notes to take at speed and timed written tests. By Years 9 and 10 the reading load is too large to memorise a way through. The student has not got worse. The work has outgrown the workaround.

What An Assessment Shows A Teenager

An assessment shows where reading and spelling are breaking down and what to work on. Dr Lauren Crumlish assesses how a teenager reads and spells and the language skills underneath, such as hearing the sounds inside words. For a teenager who has started to believe they are not clever, it can help to see the difficulty named and located.

Dr Lauren does not diagnose dyslexia. A formal dyslexia diagnosis is usually made by a psychologist, and a family who needs one will also need a psychologist’s assessment, at that provider’s fee. The difference is set out in who can diagnose dyslexia.

Exams And Adjustments: Ask The School First

The school and the state curriculum authority decide what evidence they accept for adjustments such as extra time, and the rules differ between them. Some require a psychologist’s report. If exam adjustments are the reason you are looking for an assessment, ask the school what it requires before you apply to anyone.

How A Teenager Takes Part Online

The assessment is by video. The teenager reads, spells and does listening and speaking tasks with Dr Lauren, who brings the material onto the screen. They need a computer or tablet with a camera and microphone, a steady internet connection and a quiet room. Dr Lauren lets the family know beforehand whether she would like a parent beside the teenager or nearby. The running order is in what happens on the day.

Next Steps

What To Do Now

Six steps, in order. Stop at whichever one gives you the answer you need.

  1. Go through the checklist together

    Ask your teenager which signs they recognise. Their answers often differ from yours, and theirs count.

  2. Ask the school what it sees

    Speak to the year coordinator or the learning support teacher. Ask how your teenager reads and writes in class, what help has been tried, and what evidence the school needs for adjustments.

  3. Rule out hearing and vision

    healthdirect advises having both checked, so that neither is the cause of the difficulty.

  4. Take the free screener

    A parent answers a short set of questions about the teenager. It is a screener, not a diagnosis.

  5. Arrange an assessment

    $890 or $1,290, online, with Dr Lauren Crumlish. It shows where reading and spelling break down and what to work on.

  6. If you need a formal diagnosis

    See a psychologist as well. A formal dyslexia diagnosis is usually made by a psychologist, at that provider’s fee.

Questions

Questions About Dyslexia In Teenagers

What are the signs of dyslexia in a teenager?

The main signs of dyslexia in a teenager are slow reading that needs rereading, avoiding reading aloud and spelling the same word in different ways. Written work is often much weaker than spoken answers, and tests run out of time. One sign means little. A cluster that has been there since primary school is worth an assessment.

Can dyslexia start in the teenage years?

No. Dyslexia is present from early childhood and does not develop in the teenage years. What changes in high school is the amount of reading and writing, which can expose a difficulty that a capable student managed to cover in primary school.

Can a teenager be assessed for dyslexia online?

Yes. Dr Lauren Crumlish assesses teenagers up to 18 by video, anywhere in Australia. Your teenager takes part from home on a laptop or tablet and works with Dr Lauren directly, without a parent answering for them. The assessment is $890 or $1,290. A formal dyslexia diagnosis is usually made by a psychologist.

Will an assessment get my teenager extra time in exams?

Extra time in exams is decided by the school and the state curriculum authority, not by the person who does the assessment. Each sets its own rules on the evidence it accepts, and some require a psychologist’s report. Ask the school what it needs before you arrange any assessment for that purpose.

Is 15 or 16 too late to find out?

No. Dyslexia is lifelong, and healthdirect states that people with dyslexia can improve their reading and spelling skills. Knowing where the difficulty lies also helps a teenager and their teachers choose what to work on in the years of school that remain.

Can dyslexia in a teenager look like laziness or ADHD?

Yes. A teenager who avoids reading, hands in short work and drifts off in class can look unmotivated or inattentive when the real cause is that reading and writing are slow and tiring. Attention difficulties can also occur alongside dyslexia, so both are worth considering.
