Implementation Challenges

Accra, 10-14 May


Introduction

Introduction

  • We will go through real challenges encountered in Gambia, Niger, Senegal;

  • We will present situations experienced and try to classify them into attrition, partial compliance, selection bias, etc;

  • Then we will propose possible solutions.


Gambia

Gambia

  • Schools in the treatment group did not receive funding for certain reasons;

  • Teachers of schools in the treatment group were reassigned to some schools in the control group and vice versa.


Niger

Niger

  • Some schools in the control group received books;

  • Difficulties of access due to heavy rains and schools closed earlier than expected. The characteristics of the two groups are identical in spite of problems.


Senegal

Senegal

  • Schools still closed when running the survey (1 month after academic year start). Security and geographic impediments prevent from reaching schools. Targeted grades not present in a few schools;

  • 2 schools out 211 moved from control group to the treatment one, receiving treatment (textbooks from a donor);

  • No school (among 11 recipients) in the treatment group of a region had received funding.


Other threats to internal validity 1

Other threats to internal validity (1)

  • Take pre-cautions prior to occurrence of threats;

  • Other threats of internal validity:

    • the quality of data collected;

    • delays in giving treatment to beneficiaries;

    • time lag between conducting baseline and follow-up;

    • rigid outcomes that do not change as a result of the intervention;

    • treatment given before baseline;

    • etc.


Other threats to internal validity 2

Other threats to internal validity (2)

  • Even if evaluation is well designed, monitoring well done, we may end up with misguided conclusions with wrong data, thus misleading decision makers;

  • Always recall : Garbage In  Garbage Out.


Other threats to internal validity 3

Other threats to internal validity (3)

  • Serious problems in the case of Senegal: almost 3 checks out of 5 were wrong;

  • Need to start over the data entry which took 10 weeks.


Conclusion 1

Conclusion (1)

  • Given the costs of the evaluation, should avoid any second best solutions; the best remedy is prevention;

  • Monitor the roll-out carefully – demand high standards of compliance with the original design (small details make a difference) ;

  • Make adjustments immediately as needed.
