Your child has been receiving SEN support for weeks or months. Reading interventions, behavior plans, speech therapy sessions. But how do you know if it’s actually working? This guide explains what progress to look for, how it’s measured, what your rights are around reviews, and when to ask for changes. Because “we’re doing interventions” isn’t enough – you need to see evidence of impact.
Part 1: Why Measuring Progress Matters
The Legal Requirement
The SEND Code of Practice is clear: “Progress towards meeting planned outcomes should be tracked and reviewed at least once a term.”
According to the graduated approach mandated by the Code, schools must:
- Set clear, measurable targets
- Monitor progress regularly
- Review outcomes at least termly
- Adjust support based on evidence
You’re entitled to know whether interventions are working. This isn’t optional.
Why Evidence Matters
According to research on progress monitoring, regular data collection helps:
- Assess student performance – where are they now?
- Quantify rate of improvement – are they improving fast enough?
- Evaluate intervention effectiveness – is this approach working?
- Make informed decisions – continue, change, or stop?
Research from Illuminate Education (2023) shows: “Without objective measures, behavior change may be too gradual to notice, or teams may continue ineffective interventions for too long.”
Part 2: What Types of Progress to Look For
Progress isn’t just about test scores. For children with SEN, you need to measure multiple areas.
Type 1: Academic Progress
What it means: Improvement in specific academic skills – reading, writing, maths, etc.
What to measure:
- Reading:
- Words read correctly per minute (reading fluency)
- Number of high-frequency words known
- Ability to decode unfamiliar words
- Reading comprehension scores
- Book band/reading level
- Writing:
- Number of words written in 5 minutes
- Correct use of punctuation and capital letters
- Spelling accuracy on target words
- Ability to write sentences/paragraphs independently
- Maths:
- Number facts known (e.g., times tables, number bonds)
- Accuracy on target skills (addition, fractions, etc.)
- Problem-solving ability
- Speed of calculation
Example of good measurement:
Target: Mia will read 20 high-frequency words from Year 2 list by end of Spring term.
Baseline (January): Knows 8 words
Week 4 (February): Knows 12 words (progress: +4)
Week 8 (March): Knows 17 words (progress: +5)
Week 12 (April): Knows 21 words (progress: +4)
Result: TARGET ACHIEVED. Intervention working.
Type 2: Behavioral Progress
What it means: Reduction in problem behaviors or increase in positive behaviors.
According to research on behavior intervention monitoring, you can track:
- Frequency: How often behavior occurs
- Example: “Number of times Sam hits per day”
- Baseline: 8 times/day to After 6 weeks: 2 times/day
- Duration: How long behavior lasts
- Example: “Length of tantrums”
- Baseline: Average 15 minutes to After 6 weeks: Average 5 minutes
- Intensity: How severe behavior is
- Scale 1-5: 1=mild fussing, 5=violent/dangerous
- Baseline: Average intensity 4 to After 6 weeks: Average intensity 2
- Positive replacement behaviors: What you WANT to see
- Example: “Number of times uses calm-down strategies”
- Baseline: 0 times/week to After 6 weeks: 4 times/week
Example of good measurement:
Target: Marcus will use calm-down strategies when frustrated, before shouting, in 3 out of 5 situations by end of term.
Baseline: Uses strategies 0/5 times (0%)
Week 4: Uses strategies 1/5 times (20%)
Week 8: Uses strategies 2/5 times (40%)
Week 12: Uses strategies 4/5 times (80%)
Result: EXCEEDED TARGET. Intervention working.
Type 3: Social and Emotional Progress
What it means: Improvement in social skills, emotional regulation, relationships, and wellbeing.
Research from Edutopia on social-emotional assessment (2016) and Child Indicators Research (2023) shows these areas matter:
- Social competence:
- Initiating play/conversation with peers
- Taking turns and sharing
- Responding appropriately to social cues
- Number of positive peer interactions
- Emotional regulation:
- Ability to identify own emotions
- Using calming strategies when upset
- Recovery time after upset
- Expressing feelings appropriately
- Self-awareness and confidence:
- Willingness to try new things
- Asking for help when needed
- Positive self-statements
- Participation in class discussions
- Relationships:
- Quality of friendships
- Comfort with adults
- Conflict resolution
Example of good measurement:
Target: Sophie will initiate play with peer by asking “Can I play?” at least once per playtime, 4 days out of 5, by end of term.
Baseline: Initiates play 0 times per week
Week 4: Initiates play 1 time per week
Week 8: Initiates play 2 times per week
Week 12: Initiates play 4 times per week
Result: TARGET ACHIEVED. Intervention working.
Type 4: Independence and Life Skills
What it means: Ability to do things for themselves.
What to measure:
- Following multi-step instructions independently
- Organizing materials without prompts
- Completing tasks without adult support
- Self-care skills (if relevant – dressing, toileting, eating)
- Problem-solving when stuck
Example:
Target: Jake will follow the morning routine checklist independently (5 steps) on 4 out of 5 school days.
Baseline: Completes independently 0/5 days (needs adult prompting for each step)
Week 6: Completes independently 2/5 days
Week 12: Completes independently 4/5 days
Result: TARGET ACHIEVED.
Make Every School Visit Count
Method 1: Baseline and Progress Monitoring
What it is: The gold standard for measuring intervention effectiveness.
According to Vanderbilt University research on progress monitoring:
Step 1: Collect baseline data – Measure the skill BEFORE intervention starts.
- Ideally take 3 measurements within a week to get reliable baseline
- Use median (middle score) of the three
- Example: Child reads 35, 40, 38 words per minute to Baseline = 38 wpm
Step 2: Set goal – Decide what you’re aiming for by end of intervention.
- Should be challenging but achievable
- Based on typical rates of progress
- Example: From 38 wpm to 70 wpm in 12 weeks (gain of 32 words)
Step 3: Monitor regularly – Measure the same skill weekly or bi-weekly.
- Use SAME method each time (for fair comparison)
- Record results
- Example: Week 1: 42 wpm, Week 2: 45 wpm, Week 3: 48 wpm…
Step 4: Graph the data – Visual representation shows trend.
- Draw line from baseline to goal (this is the “aim line” or “goal line”)
- Plot weekly scores
- If actual scores stay above aim line = excellent progress
- If actual scores follow aim line = on track
- If actual scores stay below aim line = not enough progress, need to change approach

Method 2: Curriculum-Based Measurement (CBM)
What it is: Quick, standardized probes that measure specific skills.
According to Understood.org’s guide on RTI progress monitoring, CBM includes:
- Reading fluency: 1-minute reading probe (count words read correctly)
- Maths: 2-minute probe of target skills (count problems correct)
- Spelling: 2-minute probe (count words spelled correctly)
- Writing: 3-minute writing sample (count words written)
Why CBM works:
- Quick (1-3 minutes) so can do frequently
- Standardized (same format each time)
- Sensitive to small changes
- Reliable and valid
Method 3: Work Samples and Observations
What it is: Collecting actual examples of child’s work over time.
For academic skills:
- Keep writing samples from beginning, middle, end of intervention
- Photograph maths work
- Record reading (can use phone)
- Compare over time – can you SEE improvement?
For behaviour:
- Daily behaviour charts (good day, difficult day)
- Incident logs (date, what happened, how long, what triggered it)
- Teacher/TA observations written in diary
Method 4: Standardized Assessments
What it is: Formal tests that compare child to peers.
Examples:
- Reading age assessments (York Assessment of Reading Comprehension, etc.)
- Spelling age tests
- Single word reading tests
- Standardized maths assessments
Limitations: Only done periodically (termly or yearly), less sensitive to small changes. Best used alongside regular progress monitoring.
Method 5: Rating Scales and Questionnaires
What it is: Teachers, parents, or child rate specific skills/behaviours on a scale.
Used for:
- Social-emotional skills
- Behaviour problems
- ADHD symptoms
- Anxiety/emotional wellbeing
Examples:
- Strengths and Difficulties Questionnaire (SDQ)
- Boxall Profile (social and emotional development)
- ADHD rating scales
Done at beginning and end of intervention to show change.
Part 4: What Schools Should Be Doing (Your Rights)
The Graduated Approach: Assess, Plan, Do, Review
The SEND Code of Practice mandates a four-stage cycle:
ASSESS:
- Gather baseline data on child’s current level
- Identify specific difficulties
- Involve parents and child in assessment
- Consult specialists if needed
PLAN:
- Set SMART targets based on assessment
- Decide which interventions to use
- Agree who will deliver support and when
- Set date for review
- Share plan with all staff and parents
DO:
- Deliver the interventions as planned
- Monitor progress regularly (at least weekly)
- Keep records of what’s being done
- Adjust teaching as needed
REVIEW:
- Legal requirement: At least termly (3 times per year)
- Analyze progress data
- Discuss with parents and child
- Decide next steps: continue, adjust, or stop intervention
- Then cycle begins again
What You Should Receive
At the START of intervention:
- Written support plan with clear targets
- Baseline data (where child is starting from)
- Details of intervention (what, who, when, where, how often)
- Date of review meeting
During intervention:
- Regular updates (many schools send home weekly/fortnightly sheets)
- Progress data (ideally graphs or charts showing trend)
- Informal conversations with class teacher
At REVIEW meetings:
- Invitation to attend (you MUST be invited)
- Evidence of progress (data, work samples, observations)
- Opportunity to share your observations from home
- Discussion of what worked/didn’t work
- Clear decision about next steps
- Updated support plan if continuing
What Good Review Meetings Look Like
According to DfE research on SEN support (2021):
Good Review Meetings:
- Focus on evidence not opinions (“She’s doing better” vs. “She increased from 8 to 17 known words”)
- Show you the data/graphs (not just tell you about it)
- Listen to your input (what you’ve noticed at home)
- Include child’s views (age-appropriately)
- Are honest if progress isn’t happening
- Make clear decisions about next steps
- Set new targets if continuing
- Book next review date before you leave
Part 5: How to Tell If It’s Working
Signs Intervention IS Working
Data shows upward trend
- Scores improving over time (even if slowly)
- Child is on track to meet target
- Gap between child and peers is closing (catch-up growth)
You can see change
- Child reading books they couldn’t before
- Fewer meltdowns at home
- More confident attempting tasks
- Telling you about friends/social interactions
Child is generalizing skills
- Using intervention strategies in classroom (not just 1:1 sessions)
- Applying skills at home
- Transferring learning to new situations
Teachers report progress
- Participating more in class
- Completing work more independently
- Fewer support needs
Child feels more positive
- More willing to try
- Less frustrated
- Positive statements about school/learning
Signs Intervention Might NOT Be Working
Flat or declining trend in data
- Scores staying the same week after week
- No improvement after 6-8 weeks
- Progress much slower than expected rate
You see no change in daily life
- Same struggles at home
- Still avoiding reading/homework
- Meltdowns not decreasing
Skills not generalizing
- Can do it in intervention but not in class
- Only works with specific adult
- Doesn’t use strategies independently
Child becoming more negative
- Saying “I’m rubbish at this”
- Refusing to try
- More anxious about school
Vague reports from school
- “She’s doing fine” (no data)
- “We’re working on it” (no specifics)
- Can’t show you evidence of progress
The “Rate of Progress” Question
This is crucial: According to research on intervention monitoring, for children with SEN who are behind:
“Average growth” isn’t enough. If a child is 2 years behind in reading and they make 1 year’s progress in 1 year, they’re still 2 years behind next year. They’re not catching up.
You need “accelerated growth” or “catch-up growth” – faster than typical rate to close the gap.
Example:
Child A (not SEN): Makes 12 months’ progress in 12 months = On track
Child B (with SEN, 2 years behind):
- If makes 12 months’ progress in 12 months = Still 2 years behind (gap not closing)
- If makes 18 months’ progress in 12 months = Gap closing (catching up!)
Good interventions produce accelerated growth.
Part 6: Questions to Ask at Review Meetings
About Progress
- “Can I see the data?” – Ask to see graphs, charts, work samples
- “What was the baseline and where are we now?” – Specific numbers
- “Is this the rate of progress we expected?” – On track for target?
- “How does this compare to typical progress?” – Catching up or falling further behind?
- “Has progress generalized to the classroom?” – Or only in intervention?
About the Intervention
- “Has [child’s name] attended all the intervention sessions?” – Checking fidelity
- “Who has been delivering it?” – Trained staff or inconsistent cover?
- “Has it been delivered as planned?” – Frequency and duration as agreed?
- “What evidence do we have that this approach works?” – Evidence-based?
About Next Steps
- “Based on this data, what do you recommend?” – Continue, adjust, or change?
- “What are the new targets?” – If continuing, need new SMART goals
- “When will we review again?” – Book date now
- “What can I do at home to support?” – Home-school consistency
- “If this doesn’t work, what’s our backup plan?” – What’s next option?
If You’re Concerned
- “I’m not seeing this progress at home – can we discuss why?”
- “The data shows flat progress for 2 terms – shouldn’t we try something different?”
- “How much longer will we continue this intervention if progress doesn’t improve?”
- “Should we be considering additional specialist input?”
- “Could we trial a different approach for the next half term?”
The Bottom Line
Measuring progress is not optional – it’s a legal requirement. You have the right to see evidence that interventions are working.
Good measurement has three parts: Baseline (where child starts), regular monitoring (weekly/bi-weekly data), and comparison over time (is there a trend?).
Progress isn’t just about test scores. Measure academic skills, behaviour, social-emotional development, and independence.
Average progress isn’t enough. Children who are behind need accelerated growth to catch up – the gap should be closing.
Data drives decisions. If intervention working to continue. If not working after 2 review cycles to change approach.
Start with one question: “Can I see the progress monitoring data?”
