Study summary

Secondary school completion rates remain low in many low- and middle-income countries, including Côte d'Ivoire. Limited progression through lower secondary education may affect future educational and employment opportunities. In rural areas, pass rates on the Grade 10 national examination are modest, and some students leave school before completing lower secondary education. This study will evaluate whether tutoring improves academic outcomes and school continuation in the Taabo region of Côte d'Ivoire.

Approximately 1,000 adolescents will participate in two related substudies. The first substudy will include 500 Grade 10 students identified by schools as being at risk of not passing the national examination. The second substudy will include 500 adolescents who previously attended Grades 7-9 but are not currently enrolled in school. Within each substudy, participants will be randomly assigned to one of three groups: peer tutoring, teacher tutoring, or no additional tutoring (control group).

Students assigned to tutoring may receive up to 15 sessions over approximately 6 to 8 months. Tutoring sessions will focus on reviewing core curriculum content, preparing for examinations, and strengthening academic skills.

The primary outcomes are (1) passing the Grade 10 national examination and (2) enrollment in lower secondary school in the following academic year. Secondary outcomes include grade progression, study time, academic confidence, cost-effectiveness of the tutoring models, academic and well-being outcomes among peer tutors, and other longer-term outcomes (educational attainment, early family formation, mental health).

Read the detailed description

Secondary school completion rates remain limited in many low- and middle-income countries, including Côte d'Ivoire. In rural areas, a substantial share of students do not pass the Grade 10 national examination, and some adolescents leave school before completing lower secondary education. There is limited evidence on the comparative effectiveness and cost-effectiveness of different tutoring models at the secondary level in West Africa, particularly for both currently enrolled students and adolescents who are no longer enrolled.

This study is a randomized controlled education trial conducted in approximately 25 lower secondary schools in the Taabo Health and Demographic Surveillance System (HDSS) area of Côte d'Ivoire. The study consists of two related substudies.

Substudy 1 focuses on Grade 10 students identified by schools as being at risk of not passing the national examination. Substudy 2 focuses on adolescents who previously attended Grades 7-9 but are not currently enrolled in school at the start of the academic year.

Within each substudy, approximately 500 eligible participants will be enrolled and randomly assigned at the individual level to one of three groups:

  • Peer tutoring
  • Teacher tutoring
  • Control (no additional tutoring provided by the study)

Tutoring will be delivered in small groups and may include up to 15 sessions over approximately 6 to 8 months. Peer tutors will be selected from higher-performing students nominated by school principals and randomly chosen among eligible candidates. Teacher tutoring will be delivered by trained teachers following structured lesson plans emphasizing curriculum review and examination preparation.

Primary outcomes are:

  • Passing the Grade 10 national examination (Substudy 1)
  • Enrollment in lower secondary school in the following academic year (Substudy 2)

Secondary outcomes include grade progression, attendance, study time, academic confidence, and cost-effectiveness of each tutoring model. The study will also assess academic performance and well-being among peer tutors and longer-term outcomes.

Study documents will be retained for 15 years to assess long-term education and health impacts of the intervention (educational attainment, early family formation, mental health). Long-term follow-up will occur only for participants who are registered in the Taabo HDSS.

Results from this trial will contribute evidence on scalable tutoring approaches to improve secondary school progression in rural West African settings.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Peer tutoring

    Peer tutoring led by older and higher-performing peers from the same school.

    Behavioral: Peer tutoring

  • Experimental
    Teacher tutoring

    Teacher tutoring led by trained teachers.

    Behavioral: Teacher tutoring

  • No intervention
    Control group

    Control: No additional tutoring from the study; students continue to receive the usual teaching and any school-based remedial support.

Interventions

  • BehavioralPeer tutoring

    Peer tutoring led by older and higher-performing peers from the same school implemented in small groups (e.g., 3-6 students). Tutors will be nominated by school principals and then randomly selected among eligible candidates to allow causal assessment of tutoring opportunities on tutors. Sessions will focus on: (i) reviewing core curriculum content; (ii) supporting homework and exam preparation; and (iii) building basic skills and academic confidence. Tutors will receive training on pedagogy, content, and classroom management, as well as simple monitoring tools (attendance sheets, short exercises). Student tutoring will involve up to 15 sessions, typically 1-2 sessions per week. For budgeting and planning, we assume an average of 10 sessions per student, with flexibility to increase up to 15 sessions where feasible.

  • BehavioralTeacher tutoring

    Teacher tutoring led by trained teachers and implemented in small groups (e.g., 3-6 students). Teachers will follow structured lesson plans emphasizing remedial instruction and exam-relevant material. Sessions will emphasize active learning, practice exercises, and frequent low-stakes assessments. Teacher tutoring will involve up to 15 sessions, typically 1-2 sessions per week. For budgeting and planning, we assume an average of 10 sessions per student, with flexibility to increase up to 15 sessions where feasible.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
