フィリピン人の特徴の一つに数値に弱いというのがある。リーダークラスの数値が弱いと、数値目標の分解だったり、事業計画だったり、施策の結果分析だったり、数値を伴う仕事に大きな支障を生じる。そして実際に生じている。なので、リーダークラスの数値能力を向上させる必要がある。そのトレーニングとして、SPIのような算数をやらせるのがいいのじゃないかと思い、日本のSPIに使われるような問題を英訳してやってみた。

以下のようなテストを受けさせてみた。就職活動で使われるSPIと同じようなもので、スピードも見るなら20分くらいで解かせたいところだけど、スピードは諦めているので、50分で受けてもらった。15問あって、15点満点。

結果。15人に受験してもらって、最高点は8点、最低点は0点。平均点は3.6点。うーん、せめて平均点を満点の半分の7.5点にもっていきたい。皆さんもぜひ解いてみてもらいたい。（下の問には、解答の選択肢をつけていませんが、実際には8個くらいの選択肢から選ぶ形式）
