OECD is the gift that just keeps on giving. First they brought us PISA, today they've provided us with a soi-disant global 'selfie' (p.7) in the form of the TALIS report free to download today. Global it isn't – it covers 34 countries out of the 196 in the world, but let's not be picky.

I suspect most teachers even in those 34 countries would be surprised to read that they think that 'class size only seems to have a minimal impact on teaching efficacy.' I'm still guessing here but I would think that teachers in the other 162 countries, mostly in the global South, would probably be even more surprised since thousands of them teach classes of 100 + - but hey – no-one asked their opinions.

As one of the teachers in the richer 34 myself I was also surprised at how positive I am supposed to think it is that teacher appraisals are based on student test scores (p.130).  And apparently I'm pretty shocked that '80% of teachers report that annual increments in their salaries are awarded regardless of the outcome of formal teacher appraisals' (Weatherby here). Not only that but I'm apparently mildly surprised that two thirds of teachers work in schools where no bonuses are given for good appraisals nor pay detriments for poor ones. And of course I'm disappointed that only 31% of schools sack teachers for consistent 'poor' appraisals (p.140). Obviously too many schools are not following the lead of the judge in the US Vergara case – for whom the idea of teacher tenure and due process 'shocks the conscience.'

In a tweet today Education International says: EI has been actively consulted throughout the development of #TALIS & gave feedback & recommendations on questionnaire dvlpt #OECD #unite4ed Shortly after that it tweeted: EI'll remain critical 2wards possib interpretations of #TALIS results by policy makers & media who may seek simple cclusions #OECD #unite4ed Indeed – I can't help worrying about that too – particularly as such a large chunk of the report is taken up with teacher evaluation - its uses and potential. I'm sure it will give the education reformers plenty to think about.

It's a funny thing – I'm sure I'm not alone in this - but as a teacher what I wanted most was for the children I taught to learn, to enjoy learning and to ask questions about the world they live in. I found that a lot easier when class sizes were manageable. And when it came to their leaving exams I wanted them to do as well as they could do because that would be best for them – it never occurred to me to wonder why it didn't make a difference to my bank balance.
