study (started in 1997) utilized a 33 multiple-choice question measure to assess the financial
literacy of high school seniors. This measure was utilized in research on financial literacy by Fox
et al. (2005) and Braunstein and Welch (2002). The National Council on Economic Education
study (started in 2005) utilized a 24 question measure to assess the financial literacy of high
school students and adults. The Test of Economic Literacy (1978-present) utilized 46 multiple-
choice questions to assess financial literacy among the national population. Some consider this
survey a standard worldwide measure for financial literacy (Williams, 2007; Remund, 2010).
Custom-designed surveys for primary research in financial literacy have been
developed
by Lusardi and Mitchell (2007a, 2007b) and Chen and Volpe (2002). Lusardi and Mitchell
developed three questions (
compound interest, inflation, and
diversification) to measure
understanding of basic financial concepts. In
the HRS study, alarmingly low levels of financial
literacy were found among Americans between the ages of 50 and 65 who were nearing or in
early retirement (Lusardi & Mitchell, 2007a, 2007b, 2011). Only 50% of respondents were able
to correctly answer the first two financial literacy questions, with only one-third being able to
answer all three questions.
Lusardi and Mitchell (2009, 2011) expanded their initial set of three
financial literacy
questions to 13, and identified each question as either basic or sophisticated. Three additional
basic knowledge and seven additional sophisticated questions were added
to the HRS and used in
the American Life Panel (ALP), and five questions were used in the 2009 and 2012 FINRA
National Financial Capability Study. It should be noted that in the framework for financial
literacy utilized in this research, Huston (2010) refers to sophistication as the confluence of
knowledge and skills. The Lusardi and Mitchell (2007a, 2007b, 2009, 2011) financial literacy
assessment questions differentiated sophisticated from basic questions based on a higher level of
21
difficulty rather than the application of knowledge and skills. This represents an example of
inconsistent definitions within the historical literature related to the assessment of financial
literacy.
Huston (2010) identified three main barriers to effectively measuring financial literacy.
These barriers include (a) the lack of conceptualization and definition of the financial literacy
construct, (b)
the content of the instrument, and (c) interpretation of the instrument used to
measure. Historically, only about 25% of the relevant research clearly identified and connected
the framework for financial literacy that was used (Huston, 2010). Of the 25% that did identify
and elaborate on
the construct used, most of the research interchangeably applied the definition
of financial knowledge to financial literacy. The lack of an identified construct for financial
literacy and the inconsistent application of the term greatly limit both comparability and validity
across the limited amount of existing research (Huston, 2010).
