| Teachers’ Sense of Efficacy Scale (TSES) | Tschannen-Moran & Woolfolk Hoy, 2001 | Long form: 24 items. Short form: 12 items | Three subscales: instructional strategies, classroom management, student engagement | Listed as open access on the EdInstruments repository, with the corresponding author named as the contact for permission and the instrument file |
| Teacher Efficacy Scale (Gibson & Dembo) | Gibson & Dembo, 1984 | Original 30 items, reduced to 16 items in the authors’ own factor analysis | Two dimensions: Personal Teaching Efficacy (PTE) and Teaching Efficacy, later usually called General Teaching Efficacy (GTE) | Published in a peer-reviewed journal (Journal of Educational Psychology); no dedicated licensing route, so citation plus the institution’s own permission check is the practical route |
An Education faculty running thesis cohorts against teacher self-efficacy questions has two well-established, decades-apart instruments to choose between, and a research-methods office should standardise on one as the default rather than leave the choice to whichever instrument a student’s advisor happened to use in their own doctoral work. Both instruments remain in active academic use, but they measure the construct differently enough that switching between them across a cohort’s theses makes the resulting body of work harder to compare over time. This is a different job from this site’s existing Education piece on running an alignment and operationalization review for thesis proposals: that piece covers the general committee process for checking any proposal’s hypothesis-variable-indicator chain, while this piece is about which specific, named measurement instrument a self-efficacy proposal should actually use once that process is underway.
What each instrument actually measures
The Teachers’ Sense of Efficacy Scale, developed by Tschannen-Moran and Woolfolk Hoy and published in 2001, comes in a 24-item long form and a 12-item short form, organised around three subscales: efficacy for instructional strategies, efficacy for classroom management, and efficacy for student engagement, each rated on a nine-point scale anchored from “Nothing” to “A Great Deal”. The EdInstruments listing for the scale notes that a 2012 study of beginning pre-service teachers found very high correlations between the three factors and recommended using a total score rather than individual subscale scores for that population — a methodological detail worth flagging to any student proposing to study pre-service teachers specifically rather than in-service ones. The older Gibson and Dembo instrument, published in 1984, splits self-efficacy into two conceptually different dimensions: Personal Teaching Efficacy, the belief that the teacher personally has the skills to produce student learning, and Teaching Efficacy (later usually termed General Teaching Efficacy), the belief that teaching in general can overcome external constraints such as a student’s home environment. Gibson’s original pool of 30 items was reduced to 16 items in the authors’ own 1984 factor analysis, and it is that 16-item version most later studies cite.
What should the institution confirm on licensing and permission?
TSES is listed as open access on the EdInstruments repository, which names the corresponding author, Megan Tschannen-Moran, as the contact for the instrument file and permission to use it — a clear, low-friction path a research-methods office can turn into a single templated request. The Gibson and Dembo instrument, being older and originally published directly within a journal article rather than through a maintained instrument listing, has no equivalent dedicated permission route; academic use has conventionally rested on citing the original 1984 publication, as with many older scales in education research. That convention is not the same as a documented, blanket permission, so a faculty adopting it should check its own and its target journals’ position on reproducing the item set and record the distinction — a documented open-access listing for TSES, a citation convention for Gibson and Dembo — in the bank entry itself.
Which instrument should an Education faculty standardise on first?
TSES is the stronger default for most Education thesis cohorts: it is the more recent instrument, has an open-access listing and a clear contact route, and its three-subscale structure (instructional strategies, classroom management, student engagement) maps cleanly onto categories most teacher-education programmes already use in their own coursework and observation rubrics. The Gibson and Dembo instrument remains a legitimate choice specifically where a thesis is explicitly situating itself in the older personal-versus-general efficacy literature, or where a supervisor’s own prior published work used it and a student is extending that specific research line for direct comparability. A faculty should name TSES as the default and document Gibson and Dembo as the named alternative for that specific comparability use case, rather than presenting both as equally arbitrary options. Naming a default does not remove a student’s ability to make a well-justified case for the alternative; it simply means the exception should be argued for explicitly in the proposal, referencing the specific prior study or research line it extends, rather than defaulting to whichever instrument happened to appear first in a student’s own literature search.
Long form or short form of TSES?
The choice between TSES’s 24-item long form and 12-item short form is a respondent-burden decision more than a validity one: the short form retains four items per subscale and is well-suited to a survey already combining several other instruments, where total respondent time matters, while the long form gives more granular item-level data useful if a thesis intends deeper subscale-level analysis rather than a single total score. A research-methods office should record both as available options in the bank, with a one-line rule of thumb: default to the short form when the efficacy measure is one of several instruments in a combined survey, and reserve the long form for a thesis where teacher self-efficacy is the central, sole focus of the data collection.
What should the instrument bank record for each option?
Beyond the comparison table above, a usable entry needs the full original citation, the actual contact route for obtaining the instrument and permission (for TSES, the named corresponding author), a note on which form (long or short) the faculty defaults to and why, and a record of prior theses at the institution that used either instrument, so a new student can see how it was operationalised locally. This is the same governance discipline this site has documented for governing a validated service-quality instrument bank in Hospitality and for comparing tool stacks for a Pharmacy faculty’s thesis cohort: name the option, verify what it actually requires from the source, and record it once centrally rather than per student.
What about international students or non-English-language settings?
TSES has been adapted and validated into multiple languages by other researchers since its original 2001 publication, and a bank entry for an international cohort should record any translated, separately validated version relevant to the cohort’s target population rather than assume a student can informally translate the English original without a validation step of their own. A student proposing to use a translated version found in a third-party publication should be asked to confirm that publication itself reports validity and reliability statistics for the translated version, not just a translation of the item wording, since a translated instrument without its own psychometric validation is a materially weaker methodological basis than the original English TSES with its established psychometric record.
How should the bank handle a thesis studying a specific teaching context, like special education or online instruction?
Neither TSES nor the Gibson and Dembo scale was originally developed with a specific teaching context such as special education, online or hybrid instruction, or early-childhood settings in mind, and a thesis studying one of these contexts specifically should treat the generic instrument as a starting point rather than an exact fit. The standard, defensible approach mirrors the same one this site has documented for adapting a generic service-quality instrument to a specific hospitality sub-sector: retain the instrument’s core subscale structure, adapt item wording to the specific teaching context where the generic wording does not translate cleanly (for instance, “classroom management” framed for a fully online course), and report a pilot reliability check for the adapted wording rather than assuming the original instrument’s published reliability transfers unchanged. A research-methods office should keep a running record of which context-specific adaptations have already been piloted at the institution, the same running-file approach recommended for other instrument banks on this site, so a new student studying a similar context is not starting the adaptation from a blank page.
Should a thesis report Cronbach’s alpha for the instrument as used in that specific study?
Yes, regardless of which instrument is chosen or whether it is used unmodified. Both TSES and the Gibson and Dembo scale carry published reliability figures from their own original validation samples, but those figures describe the instrument’s performance in the original study’s population, not a guarantee of equivalent reliability in a different cohort, country or teaching context. A research-methods office should require every thesis using either instrument to compute and report its own sample’s reliability statistic alongside the original published figure, framed explicitly as a check on whether the instrument performed as expected in this specific study’s population, not a formality copied from the original paper.
Where Tesify fits
None of the instrument-selection, permission-confirmation or translation-validation decisions above are ones a writing platform makes — they stay with the research-methods office and the student’s own methodology chapter. Tesify is a thesis-writing workspace already used by 9,000+ students across more than 15,000 chapters, and every chapter in it is 100% written by the candidate. For an Education faculty, that keeps the justification of the instrument choice and its reliability reporting the student’s own work, which is what a methods examiner is assessing.
Frequently asked questions
What is the difference between TSES and the Gibson and Dembo Teacher Efficacy Scale?
TSES (Tschannen-Moran & Woolfolk Hoy, 2001) organises efficacy into three subscales: instructional strategies, classroom management and student engagement. The older Gibson and Dembo scale (1984) uses two dimensions: Personal Teaching Efficacy and Teaching Efficacy, later usually called General Teaching Efficacy, a conceptually different split.
Is TSES free to use in academic research?
The EdInstruments repository lists it as open access and names the corresponding author, Megan Tschannen-Moran, as the contact for the instrument file and permission — a documented, low-friction route.
Should a faculty use the TSES long form or short form?
Default to the 12-item short form when the efficacy measure is one of several instruments in a combined survey, and reserve the 24-item long form for a thesis where teacher self-efficacy is the central, sole focus, since it supports deeper subscale-level analysis.
Why might a study of pre-service teachers use a total TSES score rather than subscale scores?
A 2012 study of beginning pre-service teachers, cited on the scale’s EdInstruments listing, found very high correlations between the three factors and recommended a total score, since this group may not distinguish clearly between the efficacy domains.
Can a translated version of TSES be used for an international cohort?
Yes, provided the translated version has its own reported validity and reliability statistics from a separate validation study, not just a translation of the item wording without psychometric testing of the translated version itself.
Is the Gibson and Dembo scale formally licensed?
It has no dedicated licensing or permission route of the kind TSES has. Academic use has conventionally rested on citing the original 1984 journal publication, so an institution should confirm its own and its target journals’ position before students reproduce the items.
What should an instrument-bank entry record for a teacher self-efficacy instrument?
The full original citation, the actual contact route for obtaining the instrument and permission, which form (long or short, where applicable) the faculty defaults to and why, and a record of prior theses at the institution that used it.
