LEARNING, LITERACY AND THE LIFECYCLE National Adult Language, Literacy and Numeracy Assessment Conference 2014, Melbourne, 1-2 May 2014 William Thorn, OECD
• Look at the relationships between literacy proficiency and education and training over the lifecycle
• Give an idea of some of the questions that the data from PIAAC can help answer
• Make some comments about implications of some findings for research policy and practice
Objectives
• Two relatively distinct phases of educational participation
– ‘initial’ education and training (mid-teens to late 20s)
– ‘adult’ or post-initial phase (from late 20s)

• Change in literacy proficiency by age appears to reflect broad stages of educational participation. We look separately at:
– 16-29 year olds, and
– 30-65 year olds

Mean score: literacy
• Two issues
– Proficiency growth and its relationship to the ‘volume’ of education taken after the age of 15
– Sorting/selection and progression through initial education
Initial education
• On average across the sample, 27 year olds have higher proficiency than 16 year olds (13.7 score points)
– Variation between countries
• Close relationship between the increment in the volume of education associated with a years increase in age and the increment in proficiency

• Differences between different age cohorts are not the same as changes within a cohort over time
• To estimate proficiency growth we need to know the literacy proficiency of the 27 year old cohort at age 16 (i.e. in 2001).
– This is not observed in PIAAC
Proficiency growth
Actual and predicted literacy proficiency for 26-27 year olds in PIAAC.

• The evidence suggests that: – there is growth in literacy proficiency after
age 15. However, the quantum is difficult to estimate.
– Growth after 15 is small compared to growth prior to 15
– Proficiency growth related to the time spent in education after 15, and
– proficiency at age 27 is related to proficiency at age 15.
Proficiency growth: summary
• Progression through secondary and post-secondary education involves both learning and sorting. – Ensuring that young people are directed to the
courses and programs that best reflect their talents and abilities is a more or less explicit goal of policy.
– Selection is explicit for many courses (e.g. entry to university.
– Young people also self-select given their interests and their perception of their ability.

• Two sets of questions
– What are the explanations for the observed decline in literacy proficiency from the age of 30 age and does education play any role in mitigating this?
– What is the relationship between participation in non-formal education and training and proficiency in literacy?
Post-initial or ‘adult’ education and training
• Changing composition of the adult population in terms of educational attainment explains some of the decline.
• However, decline is observed across all levels of attainment
– Difference between 30 and 65 year olds slightly less for people with less than upper secondary attainment.

Mean score
• Changes in educational quality
• Skills depreciation
• Age-related cognitive decline
Proficiency decline: possible reasons
• Seems unlikely as an explanation – Implausible that changes have been constant over
time, in one direction only and affect all levels of education in a similar way
– Compositional changes may occur within populations with the same level of attainment. This may help explain the fact that the proficiency gap between the 65 and 30 year olds is less for people with low levels of education.
• Increasing rates of completion of higher levels of education may mean that younger adults with low educational attainment have lower proficiency than their older peers did at the same age.
Change in educational quality?
• Possible explanation
– Evidence that practices change with age. Proportion of adults reporting that they never read a book increases with age.
– Lack of or loss of familiarity with taking tests related to age may also be relevant

• Evidence that ‘fluid intelligence’ declines with age from early adulthood.
• ‘Crystallised’ intelligence increases over much of the lifespan
• PIAAC tests may have more in common with fluid than crystallised intelligence
Age-related cognitive decline
• Observed decline seems likely to relate to cognitive decline and atrophy
• Higher levels of education do not protect against decline. – However, decline starts from a higher level.
• Does it matter? – Literacy proficiency is one factor contributing to social
functioning
– Maximum performance is rarely required
– Accumulated knowledge and experience may offset other aspects of decline
– Individuals adapt to their environment and also adapt their environment to their capacities
Summary
• Discussions about ‘adult education and training’ tend to focus questions of quantum and access. In particular:
– Investment by employers in training
– Inequalities in access, particularly, for the low educated and low skilled.
• PIAAC can shed light on the issues of access
Non-formal education and training:
inequality, inequity and the Matthew effect
• Participation relatively stable for adults aged 30-50. The fall after 50 years of age reflects falling employment rates.
• The volume of training is negatively related to age.

Age
Mean hours Average hours in non-formal education in the previous 12 months by age
• Participation and volume of training are related to both educational attainment and literacy proficiency – The more highly educated and the more
proficient do more training
• Outcome is that the gap in the volume of training undertaken by adults with high proficiency and those with poor proficiency will increase as they age

Mean hours
• Not necessarily – More proficient are more likely to be in jobs
that require more training and to have the interest in and dispositions to undertake more training.
– Cannot say that the less educated or less proficient ‘need’ more training than their better educated/more proficient peers.
• Better to address the question of the adequacy of provision.
Is inequality inequity?
• Range of approaches to the question – Unmet demand
– Assessments of need
– Effectiveness of provision
• Unmet demand (excess of demand over supply) – Surveys generally show little unmet demand for training
among low skilled adults. To the extent that such adults want to do more training, but are unable to do so, the reasons relate to issues that prevent them actualising a demand (e.g. they don’t have the time) rather than lack of supply.
– Surveys of employers show similar findings. There is a perceived need to provide literacy training for example. However, this is often not translated into training because of the costs (both direct and in terms of foregone output).
Adequacy of supply (with a focus on
literacy related training)
• Global assessments of need
– Based on judgements about evolution of technology, the economy and society and resulting needs for skills
– Can come up with big estimates (e.g. OECD, SCOTESE in Australia)
Adequacy of supply
• Effectiveness of literacy programmes
– Evidence of proficiency gains patchy
– Programmes need to be of sufficient duration (100 hours plus)
• Summary
– ‘Adequacy’ a matter of judgement to a large degree
– Should not discount the views of the principal agents (adults with low proficiency and firms)
Adequacy of supply
• Importance of schooling for literacy proficiency
• The duration/cost dilemma for adult literacy programmes
• Training is not the only response to literacy problems
• Equity in a lifelong learning context
• Peak performance is not always required
