ADHD（注意欠如多動性障害）・ASD（自閉症スペクトラム障害）・LD（学習障害）を中心とした学習に困難がある児童は、行動面の問題に比べ、学習面の問題は気づかれにくく、学びにくさへの支援が十分とは言えない状況です。その大きな要因の一つが、学習面でのアセスメントツールの不足でした。 LD-SKAIP（Screening Kit for Academic Intervention Program）は、学力のつまづきの状態と要因を3段階のステップの中で明確にし、その多様な検査結果から、個別の指導計画と教材選定、合理的配慮につながる的確な情報を得ることができます。 iPadを活用した検査であるため、子どもへの負担が少なく、また教示や分析作業の自動化、情報管理システム等により教師への負担も軽減しつつ、効率のよい、一貫した支援が可能となります。 ステップⅠでは、学校などでの支援に必要な発達の概要を把握するために、「話す・聞く」「読む・書く」「算数・その他」「行動」「社会性」の各分野別、合計93項目の「質問項目による査定」に回答し、結果を閲覧していただくことができます。

Verdict
The clearest difference is ads: LD at none against Cheating Rock's shown. Cheating Rock's advantage is device support (3 vs 1). On price, update cadence, in-app purchases and iOS requirement there is nothing between them.
