achieving students have remained constant even though there have been significant demographic<br />

changes, including, for example, an increase from 1.7% to 7.1% between 2006 and 2015 in the<br />

proportion of students who speak a language other than English or Irish. The priority given to<br />

teaching basic literacy and numeracy skills, and the supports available to struggling learners may<br />

well have contributed to ensuring that there are low proportions of lower-achieving students in the<br />

system. The return of the proportion performing below Level 2 in science to pre-2012 levels needs to<br />

be interpreted with regard to the transition to computer-based testing and the introduction of new<br />

science items. These factors have impacted on all students in Ireland taking PISA science in 2015.<br />

A different situation is emerging with regard to higher-achieving students. In the case of science, the<br />

proportion achieving Levels 5-6 in 2015 is 7.7%, just above the corresponding OECD average of 7.1%.<br />

Similarly, 9.8% in Ireland perform at Levels 5-6 on mathematics, compared with an OECD average of<br />

10.7%. Only reading literacy has significantly higher proportion performing at Levels 5-6 in 2015<br />

(10.7%) compared to the corresponding OECD average. The performance in mathematics is a<br />

particular concern since the OECD average excludes several higher-performing countries in<br />

mathematics which are outside of the OECD, including Singapore, Hong-Kong China and Japan.<br />

The relatively low proportion of higher achievers in Ireland, especially on paper-based mathematics<br />

and science, has been pointed out in reports on earlier PISA cycles (e.g., Perkins et al. 2013). In PISA<br />

2012 computer-based mathematics, students performing at the 90th percentile in Ireland achieved a<br />

significantly lower score than on average across OECD countries even though overall performance<br />

was not significantly different from the OECD average. A number of factors seem to contribute to<br />

low performance among high achievers in mathematics, including underperformance on certain<br />

mathematical content areas (Space and Shape has been a consistent problem area in previous<br />

cycles, while Change and Relationships was identified as a potential problem in 2016; a breakdown<br />

on performance in these areas is not available for PISA 2015). Another relevant factor is the high<br />

level of anxiety about mathematics among female students in Ireland (Perkins et al., 2013) which<br />

may carry over into the types of real-life problems that are encountered in PISA.<br />

The low proportion of high performers on PISA 2015 science, and a score at the 90th percentile<br />

(617.6) that is not significantly different from the OECD average (614.8), even though Ireland’s<br />

overall mean score is significantly above the OECD average, indicates that high performers in Ireland<br />

may not be achieving their potential. The transition to computer-based assessment has undoubtedly<br />

contributed to the problem. It is unclear at this stage if the change in Ireland in the proportion<br />

performing at Levels 5-6 between 2012 and 2015 (from 10.7% to 7.1%) is due in its entirety to<br />

computer-based testing or if other factors are also involved. For example, the higher-level scientific<br />

thinking processes in which students in Ireland engage may be constrained by nature of the science<br />

tasks they encounter in curriculum and other contexts.<br />

9.2.4. Gender differences<br />

The pattern of gender differences in Ireland has changed in substantive ways since earlier rounds of<br />

PISA. The gender difference on reading literacy (12.0 score points in favour of female students) is<br />

now among the smallest among participating countries, and is well below the corresponding OECD<br />

average of 26.9. Back in 2009, there was a gender difference in Ireland of 39.2 score points in favour<br />

of females in Ireland, compared with an OECD average of 24.5 score points in that year. On digital<br />

reading in 2012, female students in Ireland had a mean score that was 25.3 score points higher than<br />

that of male students, while the corresponding OECD average difference was not significantly<br />

different at 26.0 score points. The narrower gender gap in Ireland in PISA 2015 reflects a stronger<br />

performance among male students, as well as a lower score among female students. One issue that<br />
