Hattie Ranking: 195 Influences And Effect Sizes Related To Student Achievement

John Hattie developed a way of ranking various influences in different meta-analyses related to learning and achievement according to their effect sizes. In his ground-breaking study “Visible Learning” he ranked 138 influences that are related to learning outcomes from very positive effects to very negative effects. Hattie found that the average effect size of all the interventions he studied was 0.40. Therefore he decided to judge the success of influences relative to this ‘hinge point’, in order to find an answer to the question “What works best in education?”

Hattie studied six areas that contribute to learning: the student, the home, the school, the curricula, the teacher, and teaching and learning approaches. But Hattie did not only provide a list of the relative effects of different influences on student achievement. He also tells the story underlying the data. He found that the key to making a difference was making teaching and learning visible. He further explained this story in his book “Visible learning for teachers“.

John Hattie updated his list of 138 effects to 150 effects in Visible Learning for Teachers (2011), and more recently to a list of 195 effects in The Applicability of Visible Learning to Higher Education (2015). His research is now based on nearly 1200 meta-analyses – up from the 800 when Visible Learning came out in 2009. According to Hattie the story underlying the data has hardly changed over time even though some effect sizes were updated and we have some new entries at the top, at the middle, and at the end of the list.

Below you can find an updated version of our first visualization of effect sizes related to student achievement. You can compare the entries from Visible Learning (red), Visible Learning for Teachers (green) and Hattie 2015 (blue). Hattie constantly updates this list with more meta studies. Here is a backup of our first visualisation of 138 effects.

    Hi there – thanks for sharing the graphic – not sure if someone has already pointed out to you the error. You have “Classroom Behavioural” with an effect size of 0.8

    I was looking for Classroom Discussion and assume you must have got those mixed up. Classroom Behavioural has an effect size of only 0.62.

    Hope this helps with a revision of the graphic – cheers

    Hi,

    I’ve been reading a book called Spark, by John Ratey. In it, he argues that cardio exercise has a large influence on student success. Does anyone know where this might fit into Hattie’s effects, or any related studies?

  3. Graeme Miller says:

    I note that peer tutoring has a 0.55 effect but mentoring which Hattie states is a form of peer tutoring has a 0.15 effect. How can there be this level of difference? One could assume from this that mentoring is not a particularly worthwhile investment but there would be few people who have achieved eminence in their fields who were not heavily influenced by a mentor.

    • Mike says:

      “Peer mentoring” is a specific kind of program. Likewise, I’m guessing Hattie’s “mentoring” isn’t what you have in mind. If you look at mentoring programs, it’s not like having a single brilliant individual who intimately guides you throughout a period of life. This is very hard to do well in the broader school system. You need way too many mentors to be practical, not to mention paying them and matching them up. Also, not all students respond well. Great people have generally relied on and responded to mentors in their development. But try fixing up a typical student with a typical mentor, and you’ll see it hard to predict the outcome.

  4. Daniel Reeders says:

    Hello, I am about to buy the book but I wondered if someone could just quickly fill me in here on what statistic is being used to represent the effect size, e.g. r or r^2 or z? Thanks.

    • Sebastian Waack says:

      Hello Daniel,
      Hattie uses Cohen’s d to represent the effect size. Cohen’s d is defined as the difference between two means divided by a standard deviation of the pooled groups or of the control group alone.
      Cheers, Sebastian

  5. Brad says:

    OK. I am not a statistician but I have some questions about Hattie’s explanation as to how publication bias does not affect his results. You can find the questions here:

  6. Dr John Reddington Ph.D, MAPS says:

    Comprehensive school entry screening is not specifically mentioned
    by Prof. John Hattie. However certain elements are:
    Feedback, Evaluation, Classroom Behaviour, Interventions for
    the Learning Disabled, Prior Achievement, Home Environment, Early Intervention, Parent Involvement, Preterm Birth Weight, Reducing Anxiety, SES. But others are missing eg. The division of Behaviour into Internal and External, the effects of below average Speech-Language level, Resilience, etc.
    The validity of the 20 years research on Parent, Teacher and Child-based school entry screening is contained in Reddington & Wheeldon (2009)which can be sent to Prof. Hattie (also presented at the International Conference on Applied Psychology, Paris, July, 2014).
    Prof. Hattie’s hierarchies are an extremely helpful guide, and checklist, against which to compare the Parent, Teacher and Child based items of the school entry screening system.

  7. Kunal Chawla says:

    I purchased the Visible Learning book and appreciate the ranking and effect sizes.

    Although, there isnt a place anywhere in the book where the intervention labels are explained in detail.

    For instance, what does Piagetian programs mean; what do creativity programs entail; how are repeated reading programs executed?

    Is there a way I can find out more information on what the labels mean to John Hattie?

      • Mark says:

        The explanation in this link is backed up with another link – that second link is to an abstract about a study that compared Piagettian test with IQ tests so see was the better predictor of school performance. It is not very surprising that Piagetian tests were better predictors (since these correspond to school tasks more closely than those of IQ tests).
        The main problem for me is that the study does not deal with ‘Piagetian programs’ (sic) just a test. I am struggling to find an endorsement of ‘Piagetian programs’, though I can find plenty of studies that points out gaps in Piaget’s approach – including Piaget’s own admission (late in life, but all the more creditworthy to acknowledge at that stage) that he was wrong about language being secondary to learning.
        Where are these studies that show strong effect sizes for Piagetian programmes?

  8. Kendra Henry says:

    Hi Mr. Hattie,
    How was your ranking calculated mathematically?

    Do you use the data from visible learning to make your calculations?

    Would you take video submissions to run through your visible learning process complete with transcripts and data analysis?

    Is there a charge for visible learning?

    How long does it take to get feedback?

    I’m fascinated by the idea that you are quantifying teaching strategies and want to better understand the process.

    Thanks,
    Kendra Henry

One of the biggest takeaways from my year with Ms. A had to do with assessments, particularly how to “grade” them. Gone were the days of tabulating points. In came written feedback. I’m not talking about “Nice job!” or “There is an error here.” Descriptive feedback is an extension of scaffolding.
