Through Innovative Interventions: Evidence from
Canadian Field Experiments

Reducing Barriers to Postsecondary: The Need
for Hard Evidence
 Improving access to PS important for many reasons:
• Private gains (Card, 1999; many others..)
• Societal gains, including productivity enhancement (Coulombe
and Tremblay, 2006), crime reduction (Lochner and Moretti,
2004), longer life expectancy (Lleras-Muney, 2005), improved
health (Arendt, 2008), and civic participation (Milligan, Moretti,
and Oreopoulos, 2004)
• Equalizing opportunities / increasing intergenerational mobility
2
Reducing Barriers to Postsecondary: The Need
for Hard Evidence
 The Canadian literature has successfully identified several
important barriers to PS:
•
•
•
•
3
Income (Frenette, 2008)
Financial literacy (Frenette and Robson, 2011)
Academic performance (Frenette, 2008)
Career information (Frenette, 2009)
Reducing Barriers to Postsecondary: The Need
for Hard Evidence
 Although all four barriers are amenable to policy intervention,
we have little to no hard evidence on best practices in
Canada:
• Students who qualify for grants or participate in academic /
career counseling are likely a select group
• Lack of natural experiments in Canada
• Field experiments, using random assignment, are ideal, but
rare…
4
The Canadian Millennium Scholarship Foundation
Recognized the Need for Hard Evidence
(and they had hard cash!!!)
 Commissioned the Social Research and Demonstration
Corporation (SRDC) to design, implement, and evaluate
three interventions to reduce specific barriers to PSE:
• BC AVID
– Academic intervention for middle-achieving students
• Learning Accounts (Future to Discover)
– Early promise of a large non-repayable grant for low-income
students
5
• Explore Your Horizons (Future to Discover)
– Career / education information
AVID
 Advancement Via Individual Determination (AVID)
 Serves 400,000 students in 4,500 schools worldwide
 Goal: raise academic performance, and subsequently,
university attendance
 Targets students on the margin
• Mostly Bs and Cs (middle-achieving)
• No extreme behaviour issues
• Desire to attend university
6
AVID
 What is AVID?
• Academic intervention
• Elective class (replacing a regular elective) offered throughout
high school
• Consists of:
– Curriculum studies (40%)
– Tutorials assisted by local college students (40%)
– Motivational activities regarding PS (20%)
7
AVID
 Mechanisms through which AVID may help students (Dunn et
al., 2008)?
• Study skills (time management, note taking, etc.)
• “Untracking” students (students choosing advanced courses)
• Mentoring effects (continued contact with AVID teacher and
tutors)
8
• Peer effects (continued contact with students sharing similar
characteristics)
AVID
 Can AVID make a difference?
• Cognitive skills are not malleable after age 14 (Heckman, 1995),
when AVID begins
– But AVID helps students use their existing cognitive skills more
efficiently by helping them become better learners
• Furthermore, non-cognitive skills (motivation, self-discipline) are
controlled by the prefrontal cortex, which is malleable until late
adolescence (Heckman, 2000; Shonkoff and Phillips, 2000)
9
AVID
 Non-experimental evidence on AVID’s effectiveness:
• Mehan et al. (1996):
– Improvements in college participation
• Watt et al. (2006)
– AVID districts in Texas saw gains in graduation rates, advanced course
enrollments, and international baccalaureate testing
• Watt et al. (2007)
– AVID participants had higher aspirations, knowledge about college, and
academic preparation compared to peers
• Nagaoka and LaForce (2010)
– Propensity score matching study in Chicago
– Small improvements in English and Math in grade 9; fewer absences
 All suffer from selection bias
10
• Those most likely to benefit from AVID will sign up
BC AVID
 First (and only) scientific evaluation of AVID
 1,241 students recruited at 14 BC high schools*
• Two cohorts (2005 and 2006) followed throughout HS and until
university age
• Administrative and survey data used for follow-up
 ‘AVID eligible’ students recruited through rigorous process:
• Middle-achieving (mostly Bs and Cs)
• No extreme behaviour issues
• Desire to attend university
*Schools and students had to apply to participate and waiting lists were created when classes reached
the limit of 30 (just like the real AVID). Informed consent was also required from the parents to collect data.
11
Evaluation approach
 Random assignment within high schools
 Impact:
• Treatment group outcome – Control group outcome
• Controlling for baseline characteristics
12
Focus of this study
 Impact of the offer of AVID on highest level of education
aspired*:
• Early demand indicator
 Future work will report on university / college application
/ attendance
* “No matter what you plan to be doing in a year from now (grade 12), what is the highest level of education you would like to get?”

Potential biases/evaluation challenges
Those we can rule out

Program take-up
•

Spillover of AVID techniques
•

17
Very minor issue based on earlier comparison with similar non-AVID schools (Cornell notes)
Attrition bias (survey data analysis only)
•
•

96.7% accepted AVID offer
19.6% (treatment) vs 23.8% (control) between grade 9 and 12
No important changes in baseline characteristics
Teacher grading bias
•
•
AVID students are well known
Argument does not apply to differences in sub-group impacts
Potential biases/evaluation challenges
Those we can not rule out

Program drop-out
•
•

Substitution bias (displacing non-experimental treatment)
•

Earlier report found reverse: course load was more challenging among treatment group
Timing
•
•
18
37.6% withdrew by grade 12 (mostly in that year: wanted to pick other courses to apply
skills)
Estimated impacts = Intention-to-treat effects
•
Lagged effect
Students coped with more difficult course load as they were only beginning to learn AVID
skills
AVID now being run before HS in some jurisdictions
Potential biases/evaluation challenges
Those we can not rule out

Reactions to inequity caused by randomization
•
•

Sample size
•
19
Positive or negative impact on control group
Currently following outcomes of similar students in matched non-AVID schools
Affects statistical significance (especially in sub-group analysis)
BC AVID Final Report
 Final report (including cost-benefit study) in 2013
20
Future to Discover Overview
 Two interventions designed to increased PSE access:
• Learning Accounts
– Early promise of non-repayable grant (up to $8,000) for low-income youth
– Offered in NB
• Explore Your Horizons
– Career and PSE planning intervention
– Several components (workshops, magazines, parental outreach, etc.)
– Offered in NB and MB
21
How Can Learning Accounts Help?
 Reduces cost of post-secondary, like other grants (clawedback from loans)
 Potentially addresses several design issues with existing
grants:
– Students are informed of the grant
– Early promise of aid
– No obligation to apply for loans
o May encourage loan averse students to seek grant
 Palameta and Voyer (2010)
 Lab experiment: 5-20% students rejected grants when couple with a loan
offer, but accepted same grant without loan offer (even though loan could
be forfeited without compromising grant)
o With no loans, Learning Accounts represents additional aid
22
How Can Explore Your Horizons Help?
 Informs students of costs and benefits of PSE
• Financial literacy of students very poor regarding PSE (Frenette
and Robson, 2011)
 Helps students understand educational requirements for the
careers they wish to pursue
• Knowledge of educational requirements an issue for many
students (Frenette, 2009)
23
Methodology
 Students are randomly assigned to receive the intervention
(treatment group) or not (control group)
 Three possible interventions:
• LA
• EYH
• LA + EYH

Why did Learning Accounts work in Francophone
sector?
 Possible explanation: supply constraints
 Data from New Brunswick government:
• Anglophone programs were oversubscribed
• Francophone programs were undersubscribed

Potential biases/evaluation challenges

Program take-up/drop-out
•
•

Spillover effects
•
•

33
Not an issue for LA
EYH workshops held after class
Substitution bias (displacing non-experimental treatment)
•
•

Everyone received offer of LA, but about 30% did not remember a couple of years later
Attendance in EYH workshops was poor, especially in Manitoba
– Non-mandatory, after school
Minor impact in LA (small reduction in non-repayable aid for some groups)
EYH: looking into it
Attrition bias
•
Enrolment numbers use administrative data
Potential biases/evaluation challenges

Reactions to inequity caused by randomization
•
•

Sample size
•

Positive or negative impact on control group
No mechanism for testing this (did not follow non-experimental schools)
Affects statistical significance (especially in sub-group analysis)
Future to Discover Final Report
