Penelitian ini bertujuan untuk menguji model teoritik pengaruh mediasi keterampilan sosial siswa pada pengaruh keterlibatan orang tua terhadap prestasi akademik siswa berkebutuhan khusus di sekolah dasar inklusif. Prestasi akademik siswa diukur dengan menggunakan Scale of Perceived Academic Achievement SPAA dan skala kompetensi akademik dari alat ukur Social Skills Improvement System SSIS . Keterlibatan orang tua diukur dengan menggunakan alat ukur Family Involvement Questionnaire FIQ . Keterampilan sosial diukur dengan menggunakan skala keterampilan sosial parents dan teachers form dari alat ukur SSIS. Partisipan dalam penelitian ini adalah orang tua dari siswa berkebutuhan khusus di sekolah dasar inklusif N=365 dan guru kelas N=210 yang mengajar siswa berkebutuhan khusus di sekolah dasar negeri dan swasta inklusif di lima wilayah Kota DKI Jakarta. Hasil penelitian menunjukkan bahwa keterampilan sosial memediasi pengaruh keterlibatan orang tua terhadap prestasi akademik siswa berkebutuhan khusus di sekolah dasar inklusif. Hasil ini menunjukkan bahwa keterlibatan orang tua memengaruhi prestasi akademik siswa melalui keterampilan sosial yang dimiliki siswa berkebutuhan khusus di sekolah dasar inklusif. Akan tetapi keterampilan sosial hanya memediasi secara parsial, yakni keterlibatan orang tua tetap kuat dan signifikan memengaruhi prestasi akademik siswa berkebutuhan khusus di sekolah dasar inklusif. Hasil penelitian ini menyarankan agar keterlibatan orang tua dan keterampilan sosial siswa menjadi fokus utama pihak sekolah dalam meningkatkan dan mengoptimalkan prestasi akademik siswa berkebutuhan khusus di sekolah dasar inklusif.
